I am wondering if anyone else gets a whistling sound off the passenger side. I know it's not the window because I can hear it regardless of the window being open or closed. Any ideas or similar experiences? I took off the wheel well lip the dealer put on and it does have the stoneguard but it doesn't seem to be the problem. Thanks in advance for input.

 

if it's at high speeds, then it's just how the car's aerodynamic (or lack thereof) is. it makes slight noises around the side mirrors.

 

I have an 03 also, but no whistling sounds. Could you give us a little more info, like:

- how loud is it?
- what speeds is it audible, and what speed is it most audible?

 

I do not have a sound from the passenger side while driving.

 

i have a 01 cl type s, and i get that sound too, someone told me that its the air filter

 

It it pretty noticable from 35mph to 50mph. Do they make aftermarket powered side mirrors for the 2003 Acura CL/TL? Maybe I can get those M3 style mirrors all the Civic and 3-series drivers are drooling about.
