Hi guys!

I'm hearing a whistle noise after installing the APR intake. It only happens when I'm at low RPMs and give a mid throttle. As boost is building up the whistle come.
On light throttle or WOT, nothing.

I'm guessing you double-checked all the connections? Sure it's just not the sound of the intake? :p

Yeah, everything is fine and well connected.
It's like some air turbulence is creating it.

If you went from stock air box to aftermarket intake you will evidently hear more turbo related noise when going into mild/hard throttle. It is totally normal.

These cars are built to minimize noise and the stock air box plays a part in that.

I'll try to do a video. But the sound is quite subtle.

I heard this same sound after getting my APR intake. I was worried about it too. Thought it was the "dentist drill" turbo sound that comes before a turbo failure.

Realized it was completely normal. Go on youtube and search for mk7 APR intake. You can hear the exact same sound on their video. :)
