The Original. Our proven, race-wining Air-Gap design in a dual-plane manifold. Designed for Chevrolet V-8s, the award- winning RPM Air-Gap incorporates the same race-winning technology that's used on our competition intakes. The air-gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power. Includes rear water outlets, two distributor clamp locations and nitrous bosses.
