Stillen Intake Concerns

I had the same problem with my Injen CAI's when I first installed. It went away after a while though. Haven't heard it since.

Think it has something to do with the ECU re-adjusting?

So I checked again and apparently the sound is still there. But I've had my intake for about 4 months now and all I've noticed is the power gains. As far as I'm concerned, as long as no lights come on in the dash its fine

It is definetly the ECU, and its a normal running sound - not just "re-adjusting". Took some time, and talks with a NISMO tech to really understand it.

The tech explained that the majority of the 370 ECUs whine - they have replaced many due to customer complaints, but the noise will persist.

...but I agree - if I can't hear it in cabin, and the car runs at 100% I'm happy.
