Ive got a BBK fenderwell CAI on mine and it whistles when I step on the gas hard. I thought the car had a bad wheel bearing until I replaced it and the noise was still there and then somebody told me it was the CAI.

i have bbk and i had mac, i prefer the mac, the bbk idiots put that plate on the intake, that has screws on the inside of the tube which slows down air flow, and + its not completely smooth in there. i prefer mac, IMO.

i have a MAC fenderwell unit and it was a beotch to get to fit correctly, but now that its in it works good and looks good, i've heard a lot of great things about bbk CAI's.... ebay ones are most likely junk
