my .02 is first of all I doubt the CAI alone gives any real horsepower, when you buy one be aware some need a tune. This tune (not a CAI) MAY void a good bit of your wtty. The reason I bought a CAI (no tune) was for the sound I'm happy with my Airaid but I bought it used. The best one is one scored used since you can get them in the classified for $150-200!
Enjoy it but once you've started making the car yours it can get expensive
