Application: This Accufab 90mm throttle body, or 90mm throttle body in combination with spacer is specifically designed for use on the 1986 – 1993 Ford Mustang 5.0L. However, there is no IAC provision or vacuum elbow on part number F90 or F90K. Each has a 4″ opening and requires 4″ tubing. If your application requires use of an IAC, we offer an Idle Air Control Relocation Adapter (Part number IACR). Also, the bolt pattern is 3.5″ bolt center to bolt center square.

Exceptional Quality: Accufab’s quality is second to none! This throttle body is CNC machined from 6061-T6 billet aluminum and the exterior is polished to an eye-catching finish. The shafts are also full body and CNC machined from stainless steel for durability and quality, with brass blades and the highest quality bushings, bearings and screws. Manufactured in the USA.

Technical Notes: Idle speed should only be set by adjusting the throttle position sensor. DO NOT adjust any screws on the throttle body. These screws are pre-set at Accufab. Accufab has several optional accessories to help adapt an Accufab 5.0L Ford style throttle body to be used with GM electronics instead of Ford electronics. For example, we offer a TPS adapter to use your GM TPS (Throttle Position Sensor).
