RPM Air-Gap

RPM Air-Gap (1500 - 6500 RPM)
Ideal from 1500-idle to 6500rpm, the RPM Air-Gap offers the same street/strip performance benefits of the Performer RPM but with the addition of Edelbrock's patented Air-Gap. The RPM Air-Gap design features an open air space that separates the runners from the hot engine oil for a cooler, denser charge for more power.
