Fast 54103 102mm Big Mouth Throttle Body with TPS for LS Applications

Fast 54103 102mm Big Mouth Throttle Body with TPS for LS Applications

• Designed to work with Fast LSXR intake manifolds
• Increases airflow via a series of innovative design changes and an enlarged opening
• 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

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 LSXRT 102 millimeter 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. In addition, these throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed up linkage and dual throttle spring mechanism ensure total throttle control. Big Mouth 102 millimeter Throttle Bodies also feature CFD optimized convolute bores to maintain low speed drivability.
