Weld S71 15×11 / 5×115 BP / 6.5in BS Polished Wheel

When it comes to improving your engine’s performance, increased airflow is a key ingredient. The FAST Big Mouth Throttle Bodies for the FAST LSXR and the LSXRT102mm Intake Manifolds increase airflow through a series of innovative design changes and a slightly enlarged throttle opening. FAST also invested significant testing and engineering resources into optimizing cross-sectional flow and eliminating airflow turbulence, especially at part throttle operation.
The Fast Big Mouth 102mm throttle body provides increased airflow through a smoother offset blade pivot. In addition we increased blade thickness to eliminate deflection and a beefed up linkage and spring mechanism.
Designed to work with FAST LSXR Intake Manifolds; Increases airflow via a series of innovative design changes and an enlarged opening; Offer increased throttle blade thickness to eliminate deflection ; Smoother operating offset blade pivot improves throttle response; Beefed up linkage and dual throttle spring mechanism ensure total throttle control
