Product Description

The aFe 46-39108 is an 85mm billet throttle body engineered to improve airflow over the factory 80mm unit across a range of Ford V8 platforms, from the Mustang GT and Dark Horse to F-150 and Super Duty trucks. The larger bore increases air volume delivered to the engine, translating to gains in horsepower and noticeably sharper throttle response, particularly as additional supporting modifications are added.

Machined from billet aluminum for strength and long-term durability, this throttle body is a plug-and-play, direct bolt-on installation that uses all factory mounting locations and electronics - no tuning is required for most applications. Installation typically takes about 30 minutes and requires no special tools beyond basic hand tools.

This throttle body suits Mustang GT/Dark Horse owners, as well as F-150 and Super Duty truck owners running the compatible V8 engines, who want a straightforward airflow upgrade without the complexity of a full intake or tuning package. California residents should note this part is not currently CARB exempt and cannot be purchased or used on California-registered vehicles.
