intake manifold;polished s.b. chevy performer air gap manifold

Performer Air-Gap intake manifolds incorporate technology from Edelbrock's potent Victor series manifolds, with an air-gap design feature for ultimate street performance from idle to 5,500 rpm. The air-gap is an open air space that separates the runners from the hot lifter-valley cover. This results in a cooler, denser charge, meaning more power and excellent throttle response throughout the power band.
