The First Dual-Plane Manifold with the Powerful Air-Gap Design Edelbrock has brought race-inspired technology to the street, again! The RPM Air-Gap is a dual-plane intake manifold with a dropped plenum divider that separates the intake runners from hot engine oil in the lifter valley. This provides a cooler, denser air/fuel charge for more power.
