TSP’s dual-plane air gap intake manifold for the small block Chevy is ideal for high-performance applications. Its improved design is complimented by an open area under the plenum. This feature ensures less heat transfer from the engine, meaning the air/fuel charge will be cooler and produce more power and torque.

Producing power and torque comparable to single-plane manifolds, it improves drivability and throttle response like other dual-planes and performs best between 1,500 and 6,500 rpm. It is cast from lightweight aluminum and features a relatively low profile for great hood clearance. Additional provisions include dual distributor hold-downs, 4 corner water ports, nitrous bosses and a square bore carburetor flange.
