Accufab 4-Barrel 6500 Polished Throttle Body

If you would like to switch from a carburetor intake to electronic fuel injection (EFI), Accufab has developed the 6500 high flow throttle body to meet your needs. The 6500 will bolt directly to most 4500 series cast intake manifolds. The base to top height dimension is 3" tall. This throttle body has no idle air control provision. Also, it's designed to use a Ford style 5.0L 1986-1993 Mustang pigtail style throttle position sensor, sold separately. Please note, some machining or grinding required to widen the upper area inside of a cast intake manifold plenum to clear the 2.56" diameter throttle body blades. Accufab has recently merged part number 4B-6500 & 4B-6500S into one part only, this 4B-6500 is now the only version available measuring 3" tall. If you need more clearance, we have a spacer available.

Note: Uses 86-93 Ford Mustang 5.0L TPS we offer TPS Adapters to use GM TPS for those looking to use GM electronics.

The ultimate in big bore four barrel EFI performance parts.

Better Air Flow for More Power. The Accufab 6500 series 4-barrel throttle body uses 2.56-inch bores and flows 2,656 CFM at 28-inches.

Exceptional Quality. The Accufab 6500 throttle body is made from 6061-T6 billet aluminum and polished to an eye-catching finish. Accufab's quality is second to none! Only the best components are used for unparalleled reliability and performance. Each throttle body weighs 4 pounds, compared to up to 13-pounds for a big 4500 series carburetor. Manufactured in the USA. 6500 throttle body gasket included.

This throttle body may be used with either EFI or mechanical fuel injection. For an EFI application, the throttle body is CNC machined to use a Ford Mustang 5.0L 1986-1993 throttle position sensor (TPS). However, Accufab has an optional accessory to help adapt this Ford style TPS provision to be used with GM electronics instead. For example, we offer a TPS adapter to use your GM TPS.
