Oh...not another CAI thread. Are the not enough out there with having to clutter cyberspace with another CAI thread..........j/k
Stillen had just thrown their CAI out there to be the first on the market, well they failed in the fitment dept. You had to cut into the body of the car and then it rattled....epic fail out of the gates. They have probably fixed it by now. Yeh they have recorded the best gains prolly 3whp more than Injen, and as far as throaty sound....I would still believe Injen has that dept won....imo. So I went with Injen for the better fit and their running record with the 07-08 Z33 version dual CAI. Now that AEM has recently introduced the long tube CAi I would be interested to see their gains. I believe Z1 Motorsports was testing AEM, with a little search you could probably find the review. Also good info from SS_Firehawk above.
A lot have opted to go with Z1 silicone tubes and K&N drop in filters into the stock box setup. There is a thread out there with a gizzilion pages to read, but a lot have either sold off the CAI or opted that route as their first setup. If I had to do it again I would probably go that route also. Dunno what gains it produced, still wading thru the pages when time permits. Injen sounds good, has second best gains and is easier to access the filters, contrary to what others believe....you do not have to remove the bumper to perform maintenance on the Injen. Easy to access thru wheel well. g/l on your decision, sounds like you are going with Stillen, good choice.
