FGJQEFG Airgap Intake Manifold High Rise Dual Plane Compatible with SBC Chevy 350 400 Black

180° dual plane designs for optimum fuel distribution, have two smaller plenums that receive air from the carburetor or throttle body, which results in a higher velocity through the booster making the engine more responsive to the driver.
Cool Gap design keeps hot engine oil away from intake runners resulting in a cooler, denser charge for more horsepower, torque, and efficiency.
