I know some vehicles/engines have very restrictive intakes and as a result can really free up an easy 15-20 hp. The new Shelby GT500 KR version gained it's extra 40 hp over the standard GT500 with a free flowing cold intake. I also know that isn't always the case. Are all the "ricer's" putting the intake kits I see on their various Honda's seeing any tangible improvement in hp or at the pump........or is the intake just the first thing these "tuners" toss out? I use the term "tuner" very loosely.
