Edelbrock RPM Air-Gap Intake Manifold is designed to fit 351W (windsor) V8 equipped Mustangs.
Edelbrock designed their Edelbrock RPM Air-Gap Intake Manifold with the same race-winning design that's been used on their Victor Series competition intakes for years. The unique air-gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power.
Besides the unique air-gap design the Edelbrock RPM Air-Gap Intake Manifold features a larger cross sectional area and a taller carb flange for compatibility with large displacement, stroker 351-W based engines and includes nitrous bosses.
