Product Details

Big Mouth Throttle Body by Fast®. Big Mouth™ Throttle Bodies from FAST™ are a perfect choice for a variety of GM LS applications. Features black-wrinkle powder coating and all of the same features as FAST™ billet throttle bodies. 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. Also available with GM-style IAC and TPS.
