I have a 2000 GT just installed trick flow plenum, BBk 70mm throttle body and K&N cai i have whisling ever time i get on the throttle. Is this normal or do I have a leak somewhere. I'ts kinda annoying. thanks

Hey i know this post is kinda old but your cold air will whistle especially when it's cold mine does the same thing i have a dense charger though but thats probably what it is it only does it when you accelerate though it won't do it when it's just idleing.

its normal if you have a cold air kit. The sound is it sucking in the colder air. You wont hear it on a stock engine cuz of all the restrictions to the intake box. If dont want to hear by an o/r xpipe
