FAST 102mm Throttle Body

Fitment: LS3 Engines

Featuring the latest in throttle body design, the new FAST™ Big Mouth 102mm Throttle Body™ supplies enough air for the biggest and baddest of engines. The 102mm bore allows for increased airflow while the refined idle air control passage provides a consistent idle. The new Big Mouth Throttle Body™ has been redesigned to take advantage of the benefits to be had with the new FAST™ LSXR™ 102mm Intake Manifold. The 102mm Big Mouth features a robust throttle linkage and dual throttle return springs, as well as an offset blade pivot for consistent blade closure and improved throttle response. The increased thickness throttle blade and shaft resist deflection, especially in boosted applications.
