I installed the Nismo CAI today and now it has a slight whistle/squeak when i hit the gas quickly. Not necessarily at WOT, just if I tap the gas quickly it happens.

Is this normal?

Thanks in advance.

 

hmm only thing i can tell you is to pop the hood and recheck all your rubber tubing. make sure there is metal under each of the metal screw clamps if not you might have one tube not seated properly. also do you have the optional water diverter filer installed? i left mine off for more performance (go .01 hp!)
