The Edelbrock RPM Air-Gap intake manifold for Chevrolet 262–400 ci small-block V8s uses an open air space to separate the runners from hot engine oil, promoting a cooler, denser charge for improved power. This 7501-BP version features a reflective Black Plasma finish applied via a multi-stage automated prewash and finish process, topped with a clear powder coat for durability and easy maintenance.
