102mm Throttle Body -

The 102mm Throttle Body from FAST ELECTRONICS is a precision-engineered intake component designed for high-performance engine tuning and motorsports applications. Built for serious enthusiasts and professionals who demand exact air-metering control, this throttle body replaces restrictive OEM units and unlocks horsepower gains through optimized airflow geometry. The 102mm bore represents the sweet spot for mid-range displacement engines, delivering measurable throttle response improvement and more linear power delivery across the RPM band.

This throttle body features FAST ELECTRONICS' proprietary casting and porting design, which minimizes turbulence and flow restrictions inherent to factory units. The 102mm diameter allows larger air volumes at full throttle while maintaining precise idle control through the integral butterfly valve mechanism. Weighing just 3.15 lbs, the compact assembly integrates cleanly into most fuel-injected platforms without requiring extensive custom fabrication. The polished bore surface reduces friction and improves air velocity, translating directly to faster spool times and sharper engine response under load.

This component is ideal for LS-series, small-block, and inline engines in the 350–500 cubic inch range, as well as modern turbocharged applications requiring precision fuel delivery control. Installation pairs best with programmable fuel management systems that can optimize injector pulse width for the increased airflow. Technicians should verify intake manifold compatibility before ordering, as throttle body flange spacing varies by platform. Proper tuning with a quality engine controller ensures reliable idle quality and eliminates flat spots across the power band.
