Hi all, im new to this forum so if i leave something out, just let me know.

Right, so here is my problem:
I installed a SRI, simple. Replaced the standard rubber hose and air filter box with a s/steel one and a cone filter.

After this, things seemed to be fine.
Now, all of a sudden, there is a squeaky noice coming from the engine bay. I have wrapped the s/steel pipe with heat shield, thinking it was the pipe that was rubbing up against something, and so making the noise. Didnt help. It is at its worst when the car is idling, and when i turn off the engine, it squeaks even when the engine has stopped running. Sounds like something is letting out air, but with a high pitched squeak.

Anyone had this problem before? How did you fix it....

Thanks
