So i installed a K&N aircharger kit and the intake whistles with light throttle. Under half or full throttle, there is no whistle. I have checked and double checked all hose clamps and retightened them with no luck at solving the whistling. Any other suggestions?
that's normal, the sound you are hearing is air being sucked through the new air filter, i have the AFE magnum flow "stage 2" intake, and trust me, mine sounds like a blowoff valve for a turbo
