Edelbrock Upper Plenums for Fuel Injected Intake Manifolds
Open a New Dimension to Fuel Injection Possibilities

Edelbrock has been on the cutting edge of fuel injection in the performance aftermarket for more than 15 years. Recent advancements in stand alone fuel injection systems, like the Edelbrock Pro-Tuner, offer unlimited potential to the fuel injection consumer---from the street performance cruiser to the competition racer. To compliment their popular line of fuel injection intake manifolds and EFI systems hardware, Edelbrock has released a line of upper intake plenums to accommodate virtually any intake and throttle body combination.

Engineered in Pro-E 3D modeling software and put through the rigors of Computation Fluid Dynamic (CFD) analysis, Edelbrock's upper intake plenums for EFI applications are designed to fit and function. By testing in (CFD) Edelbrock engineers were able to tune the upper plenums to more effectively distribute airflow into the intake plenum. Five applications are being offered in various heights and styles, all of which are designed to adapt a front-mount, round throttle body to a 4150-style square-bore intake mounting pad. Edelbrock also offers a line of throttle bodies in popular 75mm, 80mm and 90mm sizes.
