Edelbrock RPM Air Gap
1500 – 6500 RPM
Designed for high perfomance street and marine with square bore carbs.
Edelbrock has brought race inspired technology to the street, again! The RPM Air Gap is a dual-plane manifold with a dropped plenum divider that separates the intake runners from hot engine oil in the lifter valley, giving you a cooler, denser air/fuel charge for more power.
