Product Description

Accufab's 90mm Throttle Body
Replace your restrictive stock throttle body with this 1986-1993 Mustang Accufab 90mm throttle body! Accufab's throttle body features a 90mm throttle opening, as well as a new and improved full body stainless steel shaft. The linkage arm is a 3-position system with a threaded ball stud to make sure your throttle blade is in the correct position at all times. Accufab includes an O-ring and IAC gasket to ensure a leak resistant seal up to 100 psi. An idle air control provision is now in place to ensure a factory idle is achieved. Accufab's exceptional quality shows in this throttle body. Utilizing 6061-T6 billet aluminum, the CNC machined throttle body is precision fit and built to last. The outside is polished to a mirror shine for a look that's guaranteed to steal the show! A brass blade, along with high quality bushings, bearings, and screws completes this 90mm throttle body for performance that lasts. Accufab manufactures this throttle body in the USA for the ultimate peace of mind!

Installation Note
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.
