I recently put an AEM CAI on my '00 civic Si, and when i'm accelerating i hear a whistling or or squeaking sound coming from the right of the car. (where the intake sticks out) but i cant tell exactly where it is coming from. probably a newbie question, as i cant find anything about it when i searched. but at least it should be easy to fix.

 

CAI's are inherently noisy by nature. Are you sure it's not just the sound of air going thru the filter?

 

hissing is normal

 

no its not a hissing like your saying, i can hear that too. this sounds similar to a loose belt. also i can only hear while i push the gas pedal, but it doesnt seem to depend on how hard i push the gas pedal

 

mine does the same thing, i heard it is normal

 

It might just be the piping rubbing against the hole it runs thru.

 

Hey,
I just got the same CAI system for an integra and I got the same noise. It does sounds like a loose belt...
Dont know what causes it but it but I hear it is something that happens sometimes....Is your car a little more responsive, I know mine is?

 

after the filter gets dirty it tend to tone down it is just the air through the filter mine does the same thin on my gsr
