This is NOT true of a commercial CAI that alters the MAF sensor environment though. That would require a retune, because the sensor does not really "see" the extra air.

Does the "Gotts" intake make that much difference? Not really. I don't seem to be able to "feel" the extra 7-8 HP it's supposed to give me. But, the engine runs very smoothly, and, it's even possible I'm getting slightly better gas mileage.

I stand corrected. I had a feeling I would learn a few things on this forum. Does the MAF sensor adjust because the filter is still after the MAF sensor? And it doesn't adjust on a CAI because the filter is before the MAF sensor?
