I am proud to announce that the prototype air intake is now installed and running on my car. It sounds and feels great! Should be finished up with all of the tooling this week and should have inventory available within 2 weeks!!! :judge:

This is a true Cold Air Intake system designed and molded to fit the Pontiac G8. Our approach was to design a system that incorporates all of the features necessary to maximize performance and air flow without regards to difficulty or tool expense. We started with an air box that is a complete, one-piece molded unit extending downward and outboard of the frame rail. This is crucial since the radiator fans fill the engine compartment with extremely hot air. The box was designed to maximize filter size while creating good alignment for the MAF sensor and the duct work to the throttle body. The open top combined with the hood seal allows the most air possible to all areas of the filter while maintaining a barrier against harmful engine and radiator heat. Also, the exposed filter looks very impressive when you pop your hood!

To get the cold air moving, we have created a transition tube that couples the air filter to the MAF sensor. It features a 6” mounting flange with a “velocity stack” design to maximize the air flow to the MAF sensor. The transition tube mounts solidly to the air box using five stainless steel screws that engage the molded-in 10-32 brass inserts. The transition mounts to the MAF sensor with a high gloss silicone hose. This unique design allows for a S&B high flow air filter with a 6” mounting flange and 6” filter length!

On the other side of the MAF sensor, a silicone hump hose absorbs the engine movement. Coupled to the opposite end of the hump hose, we have custom molded an inlet duct with a large, gentle radius that keeps the air moving smoothly. Because we already have a hump hose in the system for motor rock, we can butt our inlet tube directly to the throttle body. The inside of our tube is sized to allow the most air through while being the correct diameter to create a smooth transition for the air entering the throttle body. It is important for the tube to butt tightly to the throttle body to achieve the best flow.

Part of our quest for having the best air intake available for this car includes the option of transforming this intake into a true ram air system. For those of you that “just want more” we will be offering a separate kit to do this. Like our other components, this will be a custom molded piece that will fit your car properly and perform as it should.

From start to finish, we have strived to create a system that exceeds your expectations. Thank you for taking the time to learn about our product. Looking forward to sharing dyno results soon!!!!!:driving:

do we have a rough price on this?

Priced at? $125 haha -- SOLD OUT FOR MONTHS!

Be interesting to see how long this thread makes it. LOL My guess is the second price comes in, the thread goes bye-bye. Unless, there is some sponsor thing already being worked out.

how many more minutes do you think DODSON914? till this thread gets ERASED...

Nice, a cold air box.

Now we are talking. This intake is definatey closer to waht I was looking for. Contact the admin and create an agreement so we can continue to learn more and buy!

Ditto! I was waiting for a good sealed cold air kit to come out!

Cool!! This is what I have been waiting for to come out. I am looking forward to dyno results.

I'm curious as to the sound level... I'm trying to keep my G8 as quiet as possible... Any noticable difference from the inside when driving?

OP has been in process for advising vendor program.

Any plans to offer it with a dry filter? Oiled filter media doesn't play well with MAF sensors.

I have had no problems with oil filters in the past. Most of the time when someone has a problem with an oil filter it's because they didn't not oil it properly and added too much. Also, if you like you should be able to find a dry filter without a problem that will fit it as well.

yeah what kind of price are we looking at any idea and would love to se the results thank you

Intake looks good, but it looks like the radiator cover that I just purchased from JHP may not work. Hmmm...

Thought it might make it a bit easier to see instead of clicking the link each time to view the system.

I can't wait till this CAI is available for sale! Wasn't real excited about purchasing a "non-sealed" CAI.

looks just like the system I had on my charger. the S&B filters are really good.

Yeah some vehicles have issues with oiled media some don't. My Mustang doesn't, my Canyon was always throwing an SES light for a dirty MAF. Add to that the debate about if an oiled cotton gauze filter really filters all that well to begin with led me to raise the question.

I guess I should have asked if it will be available without a filter element. I really like the looks of this setup but don't like what looks like an oiled filter.

Looks very nice...waiting for pricing.

I don't recall any LT1 cars having issues with the oiled filters, but I was only on the Impala forum. The only car I have seen in person have an issue with it was a 2000 Maxima. I heard about it at the Ford dealership when I was working there, but never actually saw it.

Thats a very easy situation to remedy, drive it for about 500 miles and clean the MAF. Any residual/extra oil should be gone by then and you are home free. Do the same procedure after you reoil the filter :)

I'd be curious to see a comparison of the stock setup to this one (or any other CAI/Ram Intake) with the following test: At WOT, use a scan tool to measure the readings from the MAF. This should tell you if you are truely flowing more air, and if so HOW MUCH more.

Looks exactally how I imagined a Volant system looking (minus the lid).

Also is the MAF arrow pointing the wrong direction (or my imagination).

All in all looks Very well made. I'd like to see pics of the other "true ram air" system.

Also is the MAF arrow pointing the wrong direction (or my imagination).

That's not the arrow. It does kind of look like it in the pics but it's installed correctly. LOL

Chris, can you please enlighten me to the proper procedure for cleaning a maf. Ive run K&N style filters for years and never had a problem, but it would be good to know how to fix it if I ever do.

Thanks!

S.F.

It's cake! Just remove the MAF from the vehicle and hose down the internals with Contact/electronics/MAF cleaner. That type of cleaner wont leave any residue so you'll be all set! Let it dry/evaporate and reinstall.

I am pretty sure they actually make a MAF cleaner. You just pull the MAF out spray it with the cleaner wipe it off and plug it back in.

AEM went to using a dry element to remedy this very problem. I personally prefer a dry element, but to each is their own. I had an aem brute force on an 03 silverado and ran it for almost 100k miles and never had a problem. I have had oil style before too...they are messy and so much more maintenance. work harder or smarter...you decide! :turbonaughtdy_1:

It would be nice to see it offered with both. I have used the oiled element filters in the past (currently have one on my Ranger), but have been wanting to try the dry to avoid the mess.

Not to knock oil filters, but they are real messy. I work in a bank which means I dont like to get dirty. Ha! Seriosly, though, I prefer the dry filters. With the technology put into dry filters these days, they are probably even more efficient than oil filters. Plus you dont have to buy a recharge kit in addition to your filter...

Why can't you just put a dry filter on it. Are all the cone filters oiled? I have spectre filters on my truck and my modified g8 intake, I don't believe they are oiled, at least they didn't tell me to oil them.
locrzn

I could be wrong, but I don't think the S&B filters require oil.

I don't have any first hand experience with S&B oiled or not. When I first saw the pics that showed the red filter I ASSumed it was a K&N.

I am very interested in this one, it looks like a cleaner set-up than the New Era.

I'm waiting for dyno sheets and before and after IAT temp. logs.

I thought it was too, but I've never had any problems with K&N. As mentioned before apply the oil properly, and give it a little time to "Dry" before taking off in the car, which is what I've done and I've never had any problems.

But it is defiantly a cleaner setup, and I can't wait to place my order!! :D:burnout:

I ran a K&N CAI on my '95 LT1 Z28 for well over 100K miles with zero intake issues. The only issues I EVER had with that car was a tranny rebuild at 108K, a dried out/broken coil wire at over 110K and a terminal tranny failure at 127K.

As for MAF cleaner, look for any electronic cleaner that is trichloro-ethane based. It's an ODC(ozone depleting compound) so it can be slightly harder to find.

A lot of cleaners went to citrus oil bases for environmental reasons. These will leave a residue.

Seems the numbers have been posted else where on the performance of this filter
Just pulling off the dyno right know!

We Have a 400 mile brand new Pontiac
G8 that we have been beta testing a nice new Roto-Fab cold air kit. This thing is awesome Jake will post up pics and dyno graphs later. Here are the early results

Stock everything : 286 .48 HP 316.35 TRQ ....Best of multiple runs from 190*-220*

Roto-Fab cold air Intake: 304..62 HP 328.49 TRQ best of multiple runs from 190*-220*

And the best deal is we ran it from 180* down the 1/4 and here are the results.
STOCK
13.65@ 102.73
13.84@ 102.50
13.85@ 101.77

Roto-Fab Cold Air
13.54@104.31
13.52@104.09
13.53@104.01

Those where all pulled back to back with out shutting the motor off!!!


Inlet air temps dropped 9* with the cold air and only 2 * With the stock air box....


339.95 is what it will be out there for in about 10 days should be ready to ship

Assuming the Roto-Fab cold air Intake numbers are with stock ECM tune? If so, those are pretty steep gains! :drool:

Didn't realize that the dyno run was being done local in IN.

We are very pleased with the dyno results. We will post the dyno sheets (both Mustang and Dynojet results) as well as a lot more information over the weekend. We will also have sound clips and a drive by video to share with all!!!

In regards to the air filter and MAF questions, We have put over 300 miles on this combination and it has not set any codes. The S&B filter comes preoiled and is ready for installation. We will provide full service instructions for those who will be servicing their own air filters, as well as selling replacment filters for those that feel it is not worth the hassle.

Pricing will be set at $339.95. We are currently awaiting shipping confirmation on several outsourced parts. Our estimated target is currently 10-14 days on having kits available. We have had several dealer inquiries and look forward to having these kits available as soon as we can.

I would like to give a special thanks to all involved!:driving:

From the Dyno results it's right at 18/12

300 miles and no codes is by no means definitive. Can it be had without a filter? if so what would be the cost?

looks impressive!!!

What else needs to be done for that gain

Tune?

Exhaust?

Attached is a picture of the of all parts included.

Nice looking intake system. Looks like you did your homework on the box. Injection molded box isn't cheap.

That's what they said it increased with just this Intake No Tune, nothing else.

Nice gains, any group purchase discounts????:popcorn2:

These power results are from simply adding the air intake system. No tuning or any other mods have been done to the car. (YET!!!!) I have also put quite a few more miles on the car. We're over 600 miles with the air intake system installed and we have not had any codes. The car sounds awsome at wide open throttle. I have a hard time trying to keep my foot out of it. There is not any drone and you can't here any differences under partial throttle driving, and at wide open throttle, the sound is deep and bold and really wakes the car up!:boink: We had rain today, but hope to have a drive by video and sound clips done tomorrow.:us_flag:

Kevin

Sell it individual and then as a package.

IE just the CAI for 299.99 and then say a tune is 299.99

Combined all at once 499.99 etc that way people get all the performance out of the CAI.

Hurry the heck up Kevin!! I'm not getting any younger! For the power increases your CAI is producing, the price y'all are charging is CHEAP horsepower!

Tell your suppliers to hurry up or we're gonna come looking for them! :p

I am VERY interested in this.

Can we get some dyno sheets and maybe some video. I am hoping VMS can tune for it and cause it to lean out a little if it's running that rich.

We appreciate all of the interest and we are trying our best to get parts expedited so we can start shipping. It's 11:45 pm here and we just came in from the shop. We have some video we will be posting tomorrow night. I believe Kevin will be posting the dyno graphs tomorrow night (Monday) as well. We both worked on instructions this afternoon and evening. We think it's important to have thorough instructions and illustrations.
The tooling for the 4" inlet elbow going to the throttle body is now complete and textured. We went with a texture that is just a little finer than the texture on the fuse relay center because we thought it would look better with the color of the MAF sensor. It looks great on the car! Also, we decided to mold in a brass 1/4" NPT bung to connect the fitting for the 3/8" breather coming from the valve cover. It's a cleaner method than a molded nipple and allows more possibilities for other plumbing that may need to connect to the inlet. Brent at EPP brought that to our attention and it made good sense, so we went with it. Again, Kevin will be posting more info tomorrow night.

When we did the "ghetto CAI" swap last month, we noticed the A/F fatten up by a whole point...are you guys seeing the same thing?

Attached is dyno graph sheet. With the Roto-Fab cold air system installed on the car A/F was .7 richer than the factory air intake. Still some room for improvment with a tune. According to Brent at EPP, there is a lot of Torque Management in play also. The most timing we saw was 21.5. He's sure there is a lot left in it.

We had the opportunity to test this cold air intake on our dyno, and we saw almost 22 RWHP on our Dynojet 248! without tuning!! The fit and finish is excellent, and the pictures truly don't do it justice! This intake is a far cry from the bent piece of metal that typically gets passed off as an air intake system, it is a professionally made, molded plastic part that is specifically designed for the G8.

Believe me, 339.00 is very fair for the level of craftsmanship that you receive in this kit, when you get the box and open it, you're going to think you got a deal!


If anyone wants to ask some questions from someone who installed and tried one out first hand, feel free to let me know,

As soon as someone gets one, key us in on what the MPG does. Seems like it should get better from breathing easier, but then they said it increased the richness of the A/F ratio...

Just curious..
I'll probably still get one anyway...

Mike,
My brother, Ben (your neighbor) informed me about your product and I have some questions that have not been asked yet.

I’m planning on purchasing a G8 soon however with the rise in fuel prices it’s difficult to sell my wife on the G8. I currently have an 03 Envoy with a K&N FIPK Gen II and a Flowmaster muffler. That setup on my 4.2L Envoy has increased my gas mileage to an average of 24 MPG on the interstate at 70 MPH. On some rare occasions I’ve experienced 27 MPG with the windows up, no wind and a cool day (ideal conditions).

Have you done any mileage comparisons with/without your CAI? I’ve noticed some of the other posts complaining about the price, although with the price of gas increasing an increase in fuel economy when you take the lead out of your shoe may pay for the product in the long run.

I would suggest an easy run to Markle and back with the Avg MPG reset when you hit a steady 70 MPH on I69. Additionally try driving around a large nearby town for an hour with/without for the city comparison.

As much as most of us are out for the power it’s a bonus if you can get it for free, especially if it only takes less than a year for that return.

Thanks,
Chris

There will probably be a small increase in gas mileage from this intake. I would imagine with an intake/exhaust/tune you could pick up 2-3mpg with this car.

Well, the UPS man just dropped off my CAI. The quality looks GREAT! I should be wrapping up at work in the next couple of hours. I will be headed straight home to swap out the CAI and the ECM (had to visit the dealer yesterday) and probably going to do an oil change as well. Will post up the results once I am done swapping them out and get a chance to take a test drive.

Here's a link for another Group Purchase for the Roto-Fab CAI over on LS1Tech.com

I finally had the opportunity for a decent mileage test. My results were very positive. The trip was from SR 18/I-69 to Indianapolis via I-69 South to pick up my wife at the airport. I drove the first half of the trip with the stock air intake, then switched on the side of the road for the second half. The change only took about 8 minutes! The entire trip was interstate travel in the same direction, so wind, temp, etc. were very similar for both intakes. BTW, I did have a head wind for the entire trip, so mileage was probably a little low straight across the board. For each sample, I set the cruise control, reset the avg. speed/mpg, and tried to hold it for 4-5 miles. I scratched a couple samples where I encountered inclines and also scratched any samples where I had to disable the cruise control. A/C was off the entire time. I just filled up with 93 before leaving. Speeds weren't identical for my comparisons because the speedo didn't match the actual mph on the display or vice/versa.
Intake--------------avg speed/mph-----avg mpg

Stock--------------- 61.5-------------- 27
Roto-fab------------ 61.9-------------- 28.6----- +1.6

Stock--------------- 67.6-------------- 21.7
Roto-fab------------ 66.3-------------- 24.7----- +3.0

Stock--------------- 73.4-------------- 22.4
Roto-fab------------ 74.2-------------- 24.7----- +2.3

I didn't post 55-60 range because I was getting in traffic as I entered Indy. The Roto-fab intake was about 4-5 mpg better, but I think I had drafting help! I posted only three comparisons so that mph was similar for each; however, every single sample comparison netted a positive result for the Roto-fab intake.
Using round numbers, assuming $4/gal for 93, and an avg mpg of 25, here is what I would conclude:
The Roto-fab intake would increase gas mileage by an avg of at least 2 mpg. That means appr. $4 saved each 300 miles. x10=$40 for 3000 miles. x10 =$400 each 30,000 miles.
I wanted to do the same test on the way back, but years of experience as a husband told me to give my wife my undivided attention since I hadn't seen her in 2 weeks!
I posted this in response to a question. We realize some of you are looking for power and may not care about a gain in mileage if it means you have to keep your foot out of it! But virtually everyone hits the cruise control on a trip, so it's nice to know you can get some or all of your investment back when you aren't demanding performance from your G8.
We invite and encourage our customers to perform similar tests and post their results. My numbers were so good with our intake through the 55-61 mph range, I didn't even want to post them without another test! I think it would be great to hear some results from others anyway.:p

How can I get one of those CAIs?

See post#107 before their all gone.

Has anyone else done a before and after dyno run with this CAI???? I have, but would like to hear other numbers!!

What #'s did you put up?

306hp/330tq stock on Dyno jet, 312hp/330tq after CAI!!!!!:censored:

you only got 6hp and same tq? what happened to 18?

WOW! That is quite different than the stuff that was posted up.

Waiting on Kevins reply to verify a few things. Followed instructions to a T but I am at a loss. I tried to look at their dyno graph again but after closer inspection, I cant read the damn thing. It was really hard to distinguish the 2 graphs apart on the dyno jet today from a before and after stand point. Dyno run to run variation could be 2+hp either way I am sure. I will try to figure out the Dyno jet programming to post a picture. Maybe someone can tell something from that.

Hopefully one of these two pics come through. Played with the settings a little more and probably found the best spot. +9/+9, but still suprised considering that Mustang Dyno's are low, and Dyno jets should read higher. I was hoping for at least 15hp.

2nd chart with all 4 runs. 1st and 3rd runs are from 45mph punch in auto drive sport mode. 2 & 4 are in manual shift left in 4th since it is closest gear for 1:1. You need word to open these. Sorry, trying to figure out how to just show the picture. This graph shows the min and max of both runs

You got a lemon!

Only kidding.

Wonder why your results aren't much different. What tune did you have done?

NO tune!!!! CAI only!

Im stilll waiting for someone to post readings out of a scan tool of their MAF sensor with a CAI installed vs stock. If you are really flowing more air, which I assume you would with a CAI, I would expect the MAF to read higher at any given RPM.

It sure seems weird that your car fattend up on the a/f. I believe most are seeing somewhere around 11.4 with no tune...yours goes into the high 10's! It should be in the mid-upper 12's a/f. I wonder if it's not something mass-air related.

My car leaned out a bit with the CAI and picked-up what they claimed.

Do you know what kind of corrections and vehicle weight the dyno guy put in?

Kevin called me a little earlier this morning and we were talking about this problem. Since they were in the developement phase of this piece, the test subject was dynoed several times after install. It might be a case of 2 pulls on the dyno not showing any effect since my car was unable to relearn any calibrations with just the 2 pulls.

I will be going to the track next friday and I will probably put it back on the dyno next Saturday. Should be plenty of time for my car to re-calibrate itself. Maybe Kevin could explain it better, but this is what they saw while it was on the dyno with their vehicle.

I certainly appreciate the call Kevin!! Now that is customer service.

I'm interested in seeing the outcome of this.

I believe the Roto-fab car got fatter w/ a/f too. I do not know what corrections they used. I have never heard a CAI leaning it out a little, I have always heard fatter.

An intake can most definitely lean a car out. Happened with one I had on a truck a few years back. Probably just depends on how the computer responds and adjust to the intake.

I'm interested in seeing the outcome of this.

Me too... I love the quality of the intake, but if the fact of the matter is that right after install the car was dyno'd and all of the gains advertised were based off of that and not more extensive testing(IE: Driving the car giving it time to relearn), I'm not overly happy with that....

Beauty cost money. How many CAI's do you want to buy??

I will soon have 2.. Trying to figure out how to put one one each side.

Put my Roto-Fab in last night. works great

Mike,
Thanks for the MPG test. I'll order one soon after I get a G8.

Thanks,
Chris

Here it is guys. The link below includes three short sound clips of the air intake installed on my G8. There is one interior sound clip and two drive by clips from each side.

Do i have to install some sort of special bypass valve or extra filter to make sure no condensation/water gets into the engine with this cold air intake?

A buddy of mine told me that he had to custom build a bypass valve to make sure no water got into the engine of his Firebird when he installed a CAI several years ago.

Can I still get my hands on one of these? Doesn't matter to me if it's part of a group buy or a retailer. Just curious/hoping. :burnout:

Will be one of my first purchases too, though I got to get the 09 ride first! It will be a direct fit for the 09 also?

So the more I read about this CAI, the more I have to wonder if the benefit is so great that it's really worth the money. I don't drive my car that hard on a regular basis so the increased hp isn't a huge benefit for me, but it's nice to know the power's there if I need it. That being said, a few hp isn't going to make a huge difference in my everyday driving. I'm not going to be running it on the track so the benefit just isn't there for me.

And the fuel economy numbers have me concerned as well. I can get about 20 MPG driving back and forth to work. At an average of 2 MPG improvement with this CAI, it would take me almost a year (approximately 50 fill-ups and over 20000 miles) to recoup my cost of this filter at $4.00 a gallon and a cost of $339 for the CAI.

Now, my average speed is probably going to decrease when I start driving around going to the store or what have you as well. I don't even know if I'm going to see that 2 MPG improvement there at all. I don't even know if I would get the 2 MPG improvement since my average speed going to and from work is only around 45 MPH.

So here's what I'm wondering. Has anyone stuck in a K&N stock replacement filter just to see the difference it could make alone? If the improvements are close to this CAI mod, I have to wonder if anyone would consider that route instead since it would be cheaper (approximately $300 cheaper).

I just had mine installed this evening. My Viper mechanic came to my house and installed it in 45 minutes, flat. He said it fit very well and was very easy to install. If I can pick up 1 to 2 mpg, I'll be thrilled. The sound alone a CAI makes when you nail it is worth the $$, so the slight mpg gain is icing on the cake.

i dont want to HAVE to put premium in. I will buy an intake once more come out and the price comes down

i dont want to HAVE to put premium in. I will buy an intake once more come out and the price comes down

I don't either. a week from friday im getting the vms ecm/tcm tune and the rotofab installed. So i guess since i will have to run premium to see the results the car is going to be a weekend warrior or something. Ill have to redo my entire budget plan :drink:

Does any one else have similar hp gains of only 6hp or what is the deal with the intake?

We got ~20 RWHP on an otherwise stock car, just like every other shop thats tested it thus far. We were VERY skeptical of the claims as it's made more than any other intake we've ever tested on anything but it lived up to the hype! This is the reason we now sell the combo rather than developing our own intake, why fight a good thing?

Good to hear. You guys can dyno my car 2marrow when i come in for the hell of it just to add to the 20rwhp claim if you want lol.

In a serious note. Ill be adding my review 2marrow after VMS installs the tune and CAI.

You guys are so lucky to live to have a good speed shop that does G8s near you. we have squat in South Florida as far as I know, just a bunch of ricer shops.

If you have time do a baseline dyno run before adding the parts.

Ill ask them if they have time to do it. I have all the time in the world, i took of work for this lol. I wouldnt mind getting a baseline run. Would love to see what my car is doing in stock form.

So, to follow up on a point made early in this thread, has anyone found a dry filter that will work with the Roto-Fab setup?

Interesting...

Naw, this thread is OK, but your avatar is interesting............very interesting.

bump for dry filter question

So, to follow up on a point made early in this thread, has anyone found a dry filter that will work with the Roto-Fab setup?

OK, no dry filter answers I guess. Let me try another: i keep hearing about how good the install instructions are for these intakes. Does there perhaps exist a pdf or similar version?

I found a source for dry cone filters. Anyone know which size will fit the Roto-Fab CAI?

http://www.aempower.com/ViewCategory.aspx?CategoryID=93

Summit has a bunch of different styles to choose from. It is just a matter of knowing the size required.

This all appears to be for the V6 model...or am I misreading things?

I am proud to announce that the prototype air intake is now installed and running on my car. It sounds and feels great! Should be finished up with all of the tooling this week and should have inventory available within 2 weeks!!! :judge:

This is a true Cold Air Intake system designed and molded to fit the Pontiac G8. Our approach was to design a system that incorporates all of the features necessary to maximize performance and air flow without regards to difficulty or tool expense. We started with an air box that is a complete, one-piece molded unit extending downward and outboard of the frame rail. This is crucial since the radiator fans fill the engine compartment with extremely hot air. The box was designed to maximize filter size while creating good alignment for the MAF sensor and the duct work to the throttle body. The open top combined with the hood seal allows the most air possible to all areas of the filter while maintaining a barrier against harmful engine and radiator heat. Also, the exposed filter looks very impressive when you pop your hood!

To get the cold air moving, we have created a transition tube that couples the air filter to the MAF sensor. It features a 6” mounting flange with a “velocity stack” design to maximize the air flow to the MAF sensor. The transition tube mounts solidly to the air box using five stainless steel screws that engage the molded-in 10-32 brass inserts. The transition mounts to the MAF sensor with a high gloss silicone hose. This unique design allows for a S&B high flow air filter with a 6” mounting flange and 6” filter length!

On the other side of the MAF sensor, a silicone hump hose absorbs the engine movement. Coupled to the opposite end of the hump hose, we have custom molded an inlet duct with a large, gentle radius that keeps the air moving smoothly. Because we already have a hump hose in the system for motor rock, we can butt our inlet tube directly to the throttle body. The inside of our tube is sized to allow the most air through while being the correct diameter to create a smooth transition for the air entering the throttle body. It is important for the tube to butt tightly to the throttle body to achieve the best flow.

Part of our quest for having the best air intake available for this car includes the option of transforming this intake into a true ram air system. For those of you that “just want more” we will be offering a separate kit to do this. Like our other components, this will be a custom molded piece that will fit your car properly and perform as it should.

From start to finish, we have strived to create a system that exceeds your expectations. Thank you for taking the time to learn about our product. Looking forward to sharing dyno results soon!!!!!:driving:


Hey Kevin, I wanted to know what ever happened to the separate kit that would create the Roto Fab CAI into a true ram air system. I tried looking for this on the Roto Fab website but no success. I would really like to purchase that separate kit. Thanks

ya isnt roto fab suppose 2 come out with a new design or am i just thinking of something else

Good stuff!

:huh:
