Top Street Performance Dual-Plane Air Gap Intake Manifolds

Producing power and torque comparable to single-plane manifolds, the Top Street Performance dual-plane air gap intake manifolds retain the drivability and throttle response like other dual-planes and performs best between 1,500 and 6,500 rpm. The manifold's improved design is complimented by an open area under the plenum—a feature that ensures less heat transfer from the engine, meaning the air/fuel charge will be cooler and produce more power and torque. These dual-plane air gap intake manifolds are cast from lightweight aluminum and feature a relatively low-profile for great hood clearance. Additional provisions include dual distributor hold-downs, four corner water ports, nitrous bosses, and a square bore carburetor flange. Show Less
