Accufab 4-Barrel 4500-2 Black Throttle Body

If you would like to switch from a carburetor intake to electronic fuel injection (EFI), Accufab has developed a high flow throttle body to meet your needs. This 4500-2 throttle body is the same height as the legendary 4500 series but has smaller 2" brass throttle plates instead of the larger 2 1/4" found on the 4500's. This 4500-2 throttle body is a perfect compromise to the larger 4500 and smaller 4150 throttle bodies. Each throttle body is 2 inches high from the base to the top. The throttle linkage extends about 1/2" above the lip. You can get an air filter spacer to raise the filter mounting location higher.

The ultimate in big bore four barrel EFI performance parts.

Feel the Power. For those looking to to fill the gab between the 4150 and 4500, now Accufab has your solution with the all new 4500-2. This all new 4500-2 flows at approximately 1700 CFM while the larger 4500 flows at 2128 CFM and the smaller 4150 flow at 1215 CFM.

Better Air Flow for More Power. The Accufab 4500-2 has four 2" brass throttle plates, with no provision for the idle air control. This style uses a late model GM TPS (included).

Exceptional Quality. The Accufab 4500-2 throttle bodies are made from high quality billet aluminum and quality is second to none. Only the best components are used for unparalleled reliability and performance. Manufactured in the USA.
