The Edelbrock Performer EGR (Electronic Gas Recirculation) Intake Manifolds are dual-plane, low-rise intake manifolds with a 180 degree firing order and patented runner design. This patented design greatly improves torque over a wide RPM range for excellent throttle response, especially off-idle through the mid-range. The intake manifold directs the air or air-fuel mixture from the throttle body to the intake ports in the cylinder head. The flow typically proceeds from the throttle body into a chamber called the plenum, which in turn feeds individual tubes, called runners, leading to each intake port. It accepts late model water neck, air-conditioning, alternator and H. E. I. (Heat Energy Ignition).
Designed for small-block Chevrolets, the Edelbrock 2101 Features an idle speed of 5500 rpm, and dual-plane, low-rise intake manifolds and a 180-degree firing order. A patented runner design greatly improves torque over a wide rpm range, especially through the mid-range. With superb throttle response, the Edelbrock 2101 will greatly enhance the performance of your small-block Chevrolet.
Years of design and testing in the area of induction technology have given the Edelbrock team invaluable insights into which characteristics work best under what conditions. For the ultimate in quality, every Edelbrock manifold is cast at our cutting-edge Edelbrock Aluminum Foundry, and machined on computerized machining centers at Edelbrock headquarters. Whether you're building a daily driver, an ultra high-performance street machine, or full-on racecar, Edelbrock intake manifolds offer the power you need.
