FAST 54102 Big Mouth Throttle Body 102mm fits LSX, LSXR intakes
When it comes to improving your engine’s performance, increased airflow is a key ingredient. The FAST Big Mouth Throttle Bodies for the FAST LSX 92mm and LSXR 102mm 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. The FAST Big Mouth 92mm Throttle Body delivers bolton GM Gen III (LS1, LS2 and LS6) horsepower while the LSXR is designed to maximize potential performance upgrades on GM L92, LS3 and LS7 engines.
