Pontiac 350 389 400 428 455 Black Powder Coated Mid Rise Intake Manifold

Description

NEW PONTIAC 326 350 389 400 428 or 455 BLACK POWDER COATED INTAKE MANIFOLD
Description:
The Speedmaster Mid Rise Air design features the identical plenum and runner design as the normal Mid Rise. The main difference is that there is an open area under the plenum chamber. This feature is sometimes called an air gap design. The air flowing under the plenum provides a cooler charge for the incoming air with less heat transfer from the engine. This cooler air charge provides additional power and torque.
