Is the K&N vibrating against something?? Look around under there for what is making the buzzing, its something loose somewhere.

You said you put a new motor in- is it stock? cams, sprockets, etc? Where I'm headed is if the valve timing is altered, that could conceivably change the induction sound.

Collapsed PCV hose... look down under the t-stat housing and find your PCV valve. now folllow that line while the car is running and find where the line is 'pinched' together by vacuum. Replace it.. done

Does it growl when your idle and not driving? When I put my steeda on at first it did that.

Normal. I think I posted something like this a long time ago when I put my intake on but I cant find the thread. It goes away after about... 500 - 1k miles or something.

I just re-read this thing from the top and realized you have a turbo on here. Is there a waste gate, and is it operating? i.e.- could the pressure behind the turbo be too high under load (the compressor blades are cutting through air instead of moving it)? I assume you already checked for intake leaks on the boost side of the turbo... yes?

Is this loudest at high RPMs but partial throttle? If the RPM's stay constant, does the sound also stay constant?

Without actually hearing this, I'm going to venture a guess that you're hearing the normal sound of air rushing arount an almost closed throttle plate. The stock airbox muffles this sound. I'll bet it's quiet at wot.
