Big Mouth LT Throttle Bodies from FAST are a perfect choice for a variety of GM LS applications. It features black-wrinkle powder coating on top of all 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.
Designed for max effort 1986–1993 Ford Mustang 5.0 builds, this BBK Performance 80mm race throttle body creates quicker throttle response and better acceleration. It will increase airflow to your engine adding more horsepower and torque to the wheels. The 80mm throttle bore size is a great choice when used with aftermarket intake manifolds using an 80mm bore.
The serrated/helix design of the aFe Power Silver Bullet Throttle Body Spacer creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber, resulting in increased performance and improved throttle response. The serrated/helix combination design also reduces intake whistle that occurs with helix-only designs.
