FAST Big Mouth 102mm Electronic Throttle Body for GM LS3/LS7/L99/L76 (54104)
$739.95
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select GM Gen IV LS engines including LS3, LS7, L76, L77, and L99 applications.
The FAST Big Mouth 102mm Electronic Throttle Body (54104) is a clean-sheet design engineered specifically for high-performance drive-by-wire (DBW) applications. Featuring a full 102mm bore, this unit significantly increases airflow over stock components, making it an ideal match for FAST manifolds or high-flow aftermarket intake systems. Unlike modified stock units, this throttle body utilizes a proprietary high-torque motor for superior response times and a steady blade position even in high-boost environments.
Built for long-term reliability, it incorporates a dual return spring and a precision non-contact Throttle Position Sensor (TPS). The satin black anodized finish provides a durable, professional aesthetic for any engine bay.
- 102mm bore diameter for maximum airflow and reduced restriction
- Designed for GM Gen IV LS factory ECUs and aftermarket systems like Edelbrock ProFlo4+
- High-torque motor prevents blade flutter under boost
- Non-contact TPS and dual return springs for increased reliability
- Clean-sheet design with no reused stock components
- Satin black anodized finish
- Manufacturer Part Number: 54104
