ive had my PR CAI for quite a while now, and alotta people have noticed that its very loud at idle for just a CAI, and i was just wondering wut could quite possibly be causes for this? did i install it wrong? is the filter bad? is there a air leak sumwhere?

 

mine's pretty loud as well. i'm hoping that's normal, lol.

 

its normal.

 

loud at idle??? hrmm, doesnt sound normal to me

 

yea at idle, like at a light or while i have it in park, its a loud whistling HISS sucking kinda noise, i mean i know its sucking air and going through the piping makes noise...but could a bad filter cause it to be louder than normal?

I had the same hissing with my CAI. SOLUTION!! - I adjusted the throttle body bypass valve (black plastic screw on top of TB) until the hissing went away...you'll end up moving your idle a hundred rpm up or down in the process, but other than that it's an easy fix for the hiss.

 

i didnt know u could adjust idle from the tb woo hoo

 

great. thanks for the info.. i'll check that out.
