Nice look, clean install, but is the air being sucked from only that upper slit? You're not going to get anything coming in under the hood. Unless it's taking air from infront of your radiator you're missing out on the bulk of air. Also, you won't get the ram air effect either. But, it looks nifty!

I'm not sure if that slit is the only place it gets air from. But if you notice a lot of the cars over in Australia use this type.

I like it. But I think the design is owned by Orrosorm or something like that. An Austrialian company......

Lots of discussion in this thread: http://www.g8board.com/forums/showthread.php?t=15170&highlight=orssom
Search for Orssom and you'll find even more.

that's nice

I had it before then I replace it with VARARAM its much better
the problem is the tuner guy said the air is very hot
maybe because its on the top of the Radiator and it collect heats

I've got one on my 08 SSV and love. Adds a great sound, looks factory fitted and designed and adds some KW's/ HPs to boot. Combined with a mafless tune, and full zorst system, it's well worth it. Air flow is great and given it's location, doesn't suck in any water even when giving the car a good wash etc (as opposed to some others).

Probably the best on the market in aust, but given I've got, I'm biased. Did my research before hand, spoke to some performance shops and the majority recommended this one. They also come with a carbon fibre top for some extra $$ if you want that look.

And yep, it's by Orrsom, an Australian company. They also make one for superchargers too now. The only issue is heat soak when in traffic, but thats only a minor issue and once underway, the airflow is back to normal.

In order to get the full benefit from this intake you need to remove the hood seal correct?

Just the section that runs over the OTR as it will rub, but apart from that, no other mod required. Sucks like a B_____D!

is this a good mod for your buck and were do you buy it and how much$

It's my understanding that you can't but these in the States as an off the shelf extra. Somewhere in another thread it discussed the reasons for it's non availability in the US.

If you are keen to pursue, check out their web site: http://www.otrcai.com/

Drop Charlie an email and see what can be done. This can be fitted with or without a MAF, but a tune is required to get the benefits or if installing without the MAF.

Bang for buck? IMO YES, but there are other OTR out there in Aust being DusSpeed, RamJet and some fine custom made intakes all giving good results (usually in the same range of performance gains).

The OTR has overtaken any other forms of CAI as the CAI of choice in in Aust recent years.

Most set you back approx AUD600.00 for the OTR (complete).

I thought these types of intakes had a problem with water from the scoops.

Never a drop anywhere near the filter or cover plate even in the heaviest rain or when washing. Very happy with the unit around.

I know a number of people in Australia with this OTR CAI and also others who have OTR's that take air from in front of the radiator such as the Duspeed one. Nobody I know has experienced any problems with water getting into to either design. We have had lots of discussions about this particularly after torrential rain etc. No problems at all!

I have a Duspeed OTR but it is well known that both of these have similar results with performance. Choices between the two (and other good brands) are largely about appearance I think.

Having said this, some of the cheaper versions made from thin plastic deform with heat or at higher throttle with the hood closed.

Do you guys from Australia have the twin scoop hood from a G8? If not they are the cause of at least 3 engines from 3 different board members that I know of with a similer designed intake's being destroyed due to water ingestion. The problem isn't the intake its the twin scoops letting water in, then the water fills the intake when its parked for hours and it runs down into the intake manifold and when you start the engine and hit the gas you get hydrostatic lock.

I wasn't hating on the intake, not hating on the twin scoops, but rather the combination of the 2 has been shown it can kill engines.

That's an interesting problem you've noted with the G8 bonnet. Can't say that I've heard of it happening here due to the limited number of GXP (G8 lookalikes) on the road here. If that's the issue, then Calais57's OTR maybe the best option given its intake is behind the grill.


Here's vids of various OTR to give you an better of idea of the options.

The company that made the intake that killed the engine actualy came out with a shield to prevent it from ingesting water, however I still wouldn't get that type. Now as for myself I have a Vararam intake which also gets its air from behind the grill and I can tell you I've never gotten a single drop of water even behind trucks in heavy down pours.

As for heat soak being a problem with OTR intakes I would tend to think the incoming air would move too fast for it to be heated up to a point where it would have a negative effect on performance. Especialy when you're driving down the road and the air is being forced in the intake.

The heat soak only has a very minor effect at idle, but is resolved as soon as the air is being forced through when moving.
