K&N already has a replacement hi-flow air filter for the G8 GT. They say this is a rechargeable permanent filter. We will see.

Mine arrived this afternoon, with the recharge kit.

I am keeping the factory air intake system, but with a few invisible mods. If you pull the stock air filter cover off and unscrew the lower half ( 2 nuts + 1 allen screw) you can pull it out. On the underside of the airhorn that goes up to the front of the engine bay there is a rectangular thin plastic section that pops right off if you score lightly around the edge with a razor blade. Gets you about another 2.5" X 3" of air flow before the filter and sits right above a cold air opening underneath the airhorn. I'll install the new air filter tomorrow, before the trip to the tuner next week. :shiner:

Maybe someone will come out with a CAI pretty soon that's fairly reasonable...

Thanks for the heads up, but I'm looking for a CAI, not a drop in filter.

Here's the part link for those who want it.

They need to produce a FIPK for the G8GT and the new GXP to come. Also called OTR.

I emailed them to tell this just now. Hopefully, by the time I can get my 09, they will be out. Good for extra 10+ HP.

That is what I am looking for, too. So I can get rid of all of the goofy baffling they use for noise control.

Those drop ins are useless. I observe no difference with them in any of the cars I've put them in.

Well its the same vilter for the VE so thats not very suprising :)

The only advantage on the drop in vs stock, K&N will last for ever. For HP, we need the FIPK

The K&N 33-2919 fits perfectly in the airbox.
Those of you familiar with K&N will know there are a couple of choices for CAI kits, the FIPK or the 77 Series (Metal Tube). If you had a choice, what would you buy? Give me some feedback and I can pass the requests along.
....yes, I work at K&N, my car was used for fit check and dyno test will be coming...

I've always gotten the plastic versions CAI kits from K&N. The metal looks nicer, but usually seem more expensive. Also, don't they tend to conduct underhood heat into the air charge easier?

I would be on the fence with the metal tube vs plastic. It would depend on the cost difference. I do think the metal (77 Series) would look pretty cool.....

Any chance of an over-the-radiator setup like the Aussie guys have?

Any chance of a group buy for forum members (discount) for the first shipment to get the K&N name out there for the G8 (mine will see car shows and the track)?

Some testing has been done on CAIs for the G8 and the computer is VERRRRY sensitive to changes.......they are still working on a reliable CAI that wont trip up the ECU ....probally going to have it programmed anyways

Filterman-
Any updates?

I would buy the unit that would give the most HP, tune or no tune :gears:

I agree. I have a FIPK on my '02 Envoy. K&N was very cool. I bought the kit before it had the CARB certification. Then when they received it, I called up and they sent me the sticker. But now that emissions are no longer run by the state, give me the HP and that is the one I will buy. My only sugestion is tie the intake tube to the filter shroud because on my Envoy the tube rattles on the shroud.

Hi Guys,
I spoke with the Engineering VP about the idea of an OTR kit and it was well received. There have been many requests for a CAI kit. More requests raise the priority, keep sending those e-mails.

K&N has at great team of people that spend many hours tuning kits to make the best performance improvements. If they think there's more HP to be had they keep experimenting. Traditionally the FIPK kits make the most power, there are more things you can do with the subtle changes in tube size and shape to get the most out of the entire air tract. While a piece of mandrel bent tubing may seem to offer little resistance to air flow, the ability to change the velocity of the air mass at a turn by changing the tube size is a big plus. The guys have been under the hood of my car several times and I'm confident they will come up with a great design.

I'll keep you posted and try to snap a few "spy shots" when they start to dyno the designs.

Filterman, that is good news. If we can get a OTR with the MAF sensor included, that would be great. Most all of the OTR's exclude the MAF which requires a tune. Nothing wrong with a tune, but some may prefer not to.

Any ideas of how long till production?

Thanks for the details and the update!! I am looking forward to seeing what you come up with.

A friend of mine tested this on his dyno , and it is no gain in horsepower or torque at all , and didn't indicate a gain in airflow in the log . I think the stock air filter isn't that bad for airflow ?

well from personal expierence the drop in filter makes a difference maybe not on our g8's. when i had my talon tsi the car wouldnt run couldnt figure out the problem cracked open the airbox and it ran. went and got the drop in the car ran fine til a ram air got installed. so the flow has to be better then stock on some cars.

Even a full CAI is pretty worthless I've seen too much testing to confirm that those full CAI are worth 5-7 hp not 10-16 or more for some cars, absolute BS. Thos K&N's are about airflow not hp, and they make more sound so you can hear it and for many stupid people, that translates to more acceleration, worng!!! The car is not going to get quicker with 10 more hp that is not enough to feel. Just like when Borla was advertising a 25 hp gain for their exhaust systems. Sorry but no exhaust system on the planet will give you, if your lucky, any more than say 15 hp. Don't waste your $$ on CAi and ported throttlebodies, under-drive pullies and such, they're worthless and just make the folks that have these services or products richer by the minute.

Are you talking about the drop in replacement filter, or the FIPK (cold air)?

That was me.. I've probally dyno tested more intakes and intake configurations than anyone at this point. The K&N to my surprise was a null gain on the dyno. It sure did feel peppier on the street.

Any new updates on the cold air intake by K&N?
