It will, but as said before, most of that power gained comes from the fact you are modifying the tune for more air. So essentially you take a tuner+tune+CAI to make that power. But even for someone that's already tuned, it won't be more than 15 whp that you gain.I got my mom an Air raid CAI for her track pack. I agree WOT doesnt feel much different, Granted i dont drive her car enough to know, but throttle response and DD felt much more responsive. However a larger inlet, with a tune, im hard pressed to see it not make more power?
