I get a whistle from my Steeda intake that is so clean it could easily be confused with a whine, any possibility that is what you are hearing? Does it matter what throttle position you are in or is it purely RPM dependant?
Purely RPM. I can WOT and for the split second it's in that range I hear it. This just started a few hundred miles ago and I've had my Airaid in for over 10k miles.
