Does your AEM CAI make a whistle noise or is my car even supposted to sound like that? Its just that one of my bearings has been starting to die on me (throw-out bearing has been squeaking when I let my clutch out) and I'm waiting for it to make noise when I just drive normally... I would put my ear by the intake but I've had ZERO time to do anything in the past week (right now I'm at work). Thanks guys!

P.S.
You can hear it at idle a bit and when you get your RPMS up a bit more it goes away and comes back around 3k rpms and dies back down again. (around 3k its louder)

intake does tend to whistle... but i dunno about it whistling at idle... im thinking your problem is something else if you hear it whistling at idle.
