Getting an intake won't give you an power gain unless your pushing like 400whp+. It's the biggest gimmick you can get on our cars since the stock air box is actually very efficient. To maximize this efficiency just go out and get a good drop-in air filter. If you're looking for some sound, then just do the snorkel delete or if you really want, get a short ram with a heatshield. This will give you a loud intake, but no much drawback except possible increased intake temps.

CAI though, are useless and pretty much endanger your car more thank anything. With winter coming up, I sure am glad I don't have my filter sitting in the fender liner getting drenched!
