Hey all, I've got a new 2011 WRX 5dr with about 6500 miles on it and lately I've been hearing a strange noise when I first start my drive. It's more of a whistle then a whine, almost like a quiet aftermarket intake. I hear it more in the morning when the car is cold but I don't recall hearing it in the winter, it started after winter started winding down here in SE Connecticut. Specifically it happens when I press the gas pedal slightly while the clutch is engaging..and stops when the clutch is either fully disengaged or engaged. It seems to vary a bit with RPMs but I'm not 100% since its not too loud of a noise. Is this something to worry about and take to the dealer? I've seen similar posts on different car forums none with anything conclusive. Thanks for any help.
