Whistling noise on boost 2012 wrx
Hey guys. Got a question. I have a 2012 wrx and just recently I started hearing this whistling noise when I'm on boost (any gear). I only hear it on occasion mostly when it's below 40 degrees. Can anybody tell me what is causing this noise? I was thinking it was a bov leak but it only happens sometimes. I brought it to my tuner and they didn't hear anything. Thanks in advance. Otherwise everything is fine. Afrs are good, no excessive knock under fine knock learn.

That's what I was thinking, sounds like Boost Leak too me.

Why does it only happen when temps are below 40 degrees? The whistling noise starts around 5psi I'd say

I would check the coupler on tb to the intercooler. I heard the clamps get loose and then the whisle sound occur. There is a thread on here about that. Check it out.
