I get the smae thing too.....at first i thought it was the intake plennum....but now after reading your posts im reconsidering it...because mine whistles LOUD...so loud that people think I have a supercahrger.....but on a super charger its the belt that actually makes the whistle.(some times...) so im thinking its the belt's....prob not a bad thing...it hasn;t been for me and i'v had mine in for 50,000 miles...can anyone else explain it?
