Since I installed my cold air kit on my 02 supercab when u back off the throttle on the highway, it makes a loud whistling-blowing noise. I don't know whats causing it, just know its the intake. Does it need a gasket between the mass air system and the bracket where the filter bolts up. This is what I'm thinkin. All help is greatly appreciated. Thanks!!
