Cold Air Intake Noise
 

Alright, when I am slightly and slowly accelerating my intake makes a "whistling noise". If I give it a lot of gas it doesnt make the noise and if I press on the gas really fast it almost sounds like it is sucking for air for a second. I have heard others say they have this problem. Has anyone heard about this? Could it be the the filter or what? I just want to get this fixed because the whistling noise is really annoying and I know it shouldn't be doing it.

The noise is kind of like a "seeeeeeeee" whistling noise. Please help me if you can. Thanks :confused:

It's my understanding that the whistling noise is usually caused by a non-perfect fitting where the filter meets the intake. You can try wrapping around it with a decent tape to see if that fixes the problem.

As for a sucking sound when you stomp on it, if you just think for a second of how the engine works, then you'll realize that's a normal sound. You open the throttle, which causes a vacuum and the air starts sucking in, however the RPM of the engine doesn't immediately skyrocket because there's a delay between starting to suck at the intake end and actually being able to use the air for combustion in the cylinders. You may also notice a different sound when you go from high throttle and let it idle down to normal throttle, because there's a vacuum in the whole pipe, but when you close the throttle the air has nowhere to go, similar to what causes turbos to require blow-off valves (but turbos deal with much higher pressures/vacuums).

Probably just the sound of the rush of air going by the throttle body butterfly(similar to what causes a whistle to whistle), just with the new intake you are able to hear it. Because with the oem tube and resonator the sound is masked.

That's APC or AEM?

it's normal. the resonator is missing

my car has the same prob but for some reason ever 4 cyl 98-02 accord ive seen with cai has had this prob all brands do it. i have a matrix cai and accordinstyle has the aem but they both do it mines louder

normal

dont worry about it

That's totally normal...

Moving to "My car is not broken!" forum... ;)

u dont like that sound?????? man i love it!

LOL, I love that sound too!! I used to pretend it was my own lil turbo.;)

I have had the same problem with mine. It's the hose that goes from the injection to the inatake. I had to shorten it a few inches and it was fine.

whats real cool is when you find the exact rpm that makes the sound. then balance right there, and everyone thinks you have a turbo. he he.
