FAST Big Mouth LSX 102mm Billet Throttle Body with TPS & IAC - Cable Driven

$356.95

$356.95

Designed for Gen III and Gen IV LS-based engines, the FAST Big Mouth 102mm Throttle Body provides a significant increase in airflow for high-performance and boosted applications. CNC-machined from billet aluminum, this cable-driven throttle body features an increased blade thickness to eliminate deflection under high manifold pressure, a common failure point in forced induction setups.

The offset blade pivot improves throttle response and provides a smoother opening transition, while the beefed-up linkage and dual throttle spring mechanism ensure consistent, reliable control. This unit comes complete with the Throttle Position Sensor (TPS) and Idle Air Control (IAC) motor for a straightforward installation on 102mm-compatible intake manifolds.

  • Drive Type: Cable driven
  • Engine Compatibility: GM Gen III and Gen IV LS engines
