Cost-Effective, but Stylish Alternative to CNC Billet Big Mouth Throttle Bodies
Big Mouth LT 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.
