Edelbrock 7121 Performer Rpm 302 Intake Manifold

The Edelbrock Performer Rpm 302 Intake Manifolds Are Dual-Plane, High-Rise Intakes With 180 Degree Firing Order To Produce Incredible Top-End Horsepower While Retaining Good Throttle Response. Their Larger Plenums And Runners Match The Free-Flowing Exhaust, High-Lift Cams And Other Modifications Of A High Output Engine. 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. They Are Intended For High-Performance Street Engines That Run Up To 6, 500 Rpm. They Are Not For Emissions Equipped Engines.
