i have a aem SRI and today when i drove it makes a hissing sound and dont stop until im fully stopped.i never had that noise before and it just starts making that sound. and when i take my key off in the ignition it sounds like its still hissing or sucking air?people says its normal but i never had that problem before. can any one tell me whats wrong? also can anyone tell me what would i know if theres something wrong with my intake? thx

 

hissing or whistle noise? itr throttle bodies are notorious for whistle noise when any aftermarket intake is put on.

 

it hisses and when i take my key off the ign. it still hiss or sucks in air

 

they will all do it, but with a stock intake and some aftermarket ones you simply won't hear it from inside the car.

don't worry about it

thats normal

 

Open air elements allow the sound to resonate out. Where as box style setups, keep the sound muffled.
