OK guys and gals, I know there have been many a thread about CAI (Cold Air Intakes - for the newbies) but can anyone actually say what type of performance they got from theirs? I mean you hear the claims 20 hp etc but we all know that is a bunch of jazz. Not that you do not get some performance increases but how much? Anyone see quicker times? Anyone get better gas milage? or better idle? or something other than looks and sound?
