Edelbrock Performer RPM Air Gap Intake
Edelbrock designed this intake manifold to increase horsepower and torque by allowing your air/fuel mixture to run cooler. They accomplished this by raising up the intake so that there is a gap underneath the intake runners for cool air to run through. The cooler air results in a denser charge for more power. The intake has an operating range of 1,500 to 6,500 RPM.
