wow! hmm, lemme think, no, i don't think i've heard of this problem. i have gone thru 4 or 5 different Intake
s and all of different brands, trying to find the best one and i never had this problem. it should make that noise if you didn't do everything right. basically when you tap the gas it sucks in air and that's the sound you hear (Psssst). all i can suggest is to check ur connections at the throtle body and make sure the filter clamp is also tight. you might not have put that part on right and thus there is no vacum effect. this is what i think perhaps someone else has a more concrete suggestion.
