I bought my CAI from place racing and was very excited about installing it. well got it in and a friend and i proceeded to rip the car apart! Three hours later(cause neither one of us are grease monkees) realized that they sent me the wrong part. well ok fine this is cool. The problem is when I called them today they proceeded to tell me it was my fault and said that I ordered for a SE-R. so, I said fine. send me the correct part. He said no, you send me the part first when I get it back I will send you yours! so in the first place I paid $200 for the CAI then $50 for shipping overnight. Know he wants me to pay another $50 to ship it back! So, $300 dollars later I am pissed off and I can't do a damn thing about it. Cause to my knowledge no on else make a CAI for the altima.
