The Alta Performance intake system pulls cold air from the factory air ram duct in the front grille and through the vent below the windshield. This is the only aftermarket intake system that is fed a constant supply of cool fresh air. The increased supercharger whine alone makes this modification worthwhile. Your car will have a very aggressive sound at wide open throttle, but will be relatively quiet when cruising. Your engine will breathe easier, giving your car more pick-up, and horse power.
