RPM Air-Gap Small Block Ford 351W Intake Manifold, Black Plasma Finish

Edelbrock Performer RPM Air-Gap Intake Manifold for 351W Ford Small Block Windsor engines in Black Plasma finish.

The Edelbrock RPM Air-Gap 351W #7581-BP intake manifold is designed for street and high performance 351-427 c.i.d. 351W Ford V8's, the RPM Air-Gap incorporates the same race-winning design that's been used on our Victor Series competition intakes for decades. 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 #7181 for compatibility with large displacement, stroker 351W based engines. Includes bosses for nitrous and rear water crossover.  The Edelbrock RPM Air-Gap 351W #7581 intake manifold is a dual-plane, high-rise intake with a 180-degree firing order to produce incredible top-end horsepower while retaining good throttle response. The larger plenum and runners match the free-flowing exhaust, high-lift cams and other modifications of a high output engine. The Edelbrock RPM Air-Gap 351W #7581-BP also features a natural aluminum finish for a classic look. For the ultimate "Made in USA" quality, every Edelbrock intake manifold is cast and machined in the USA.
