Description
Performance. Big Mouth LT Throttle Bodies™ from FAST™ for Ford Coyote applications feature a black-wrinkle powder coating. The enlarged bore is a substantial upgrade over stock and allows increased airflow to support higher horsepower. A progressive throttle pulley enhances drivability, especially at low throttle, while a double return spring provides a solid feel and increased safety. A drive-by-cable throttle body (FAST™ Big Mouth/Big Mouth LT) is necessary for XFI™ and EZ-EFI® (or other aftermarket EFI customers) running an engine that was originally throttle-by-wire. Requires GM-style IAC and TPS and is also available with them - Part #54087.
Quality Construction. The throttle body is constructed using premium-quality materials, guaranteeing durability and longevity. Featuring a sleek black-wrinkle powder coating, this throttle body not only performs well but also adds a stylish touch to your engine bay.
Installation. Putting this Throttle Body on your ride is easy and requires no drilling.
Application. This Comp Cams Big Mouth LT 87mm Throttle Body fits all 2011-23 Ford Mustang GT models.Application Notes.
