Ok, no I have not see a lot of turbo cars, but most if not all of the ones I have seen are running a WAI. What is the reason for this, packaging? road water?. I think that a turbo would benifit from a CAI because it would help keep air temps down. Is this untrue becasue the temp difference is little and the IC would(does) take care of it? I dunno, maybe I just answered my own question.
