RPM Air-Gap 351W Intake Manifold Ford 351W, 1500-6500 rpm

Designed for street and high performance 351-400+ cid 351-W Ford, the RPM Air-Gap incorporates the same race-winning design that's been used on our Victor Series competition intakes for years. The 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. Larger cross sectional area and a taller carb flange than # ED7181 for compatibility with large displacement, stroker 351-W based engines.

• Includes nitrous bosses.
• No provision for exhaust heated chokes and no exhaust crossover.
