JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.
Broad 1500-6500 RPM Range Ideal for Street or Competition
For ultimate street performance, bolt on an Edelbrock Performer RPM Intake Manifold. A dual plane, high-rise design makes incredible power to 6500 RPM with streetable torque for great throttle response. Larger plenums and runners match the free-flowing exhaust, high-lift camshafts, and other modifications of high-output engines (especially Performer RPM Cams and Cylinder Heads that optimize performance). These intakes are not for emissions-equipped engines.
