FAST 102mm Big Mouth Electronic (DBW) Throttle Body - 54104

The FAST 102mm Big Mouth Electronic Throttle Body for GM LS Engines, designed with an upgraded motor and dual return springs for quicker response and reliability, maintains stock characteristics at idle while increasing airflow over stock.

The new FAST GM LS 102mm Big Mouth Electronic Throttle Body is designed to outperform all other aftermarket drive-by-wire throttle bodies for high-performance LS engines and look good in the process. All the benefits of the current 102mm Big Mouth throttle body are now available for drive-by-wire applications, thanks to the new GM LS 102mm Big Mouth Electronic Throttle Body. This new electronic throttle body uses upgraded components and a 102mm opening to provide a huge increase in airflow over stock especially when running a FAST manifold while maintaining stock characteristics at idle. It is designed to be plug-and-play for most stock Gen IV LS ECUs including but not limited to L76, L77, L99, LS3, or LS7. It works well with the Edelbrock Pro-Flo 4+ or any aftermarket EFI system designed to control a GM LS-style electronic throttle body. The GM LS 102mm Electronic Throttle Body is designed for increased performance and reliability with a robust throttle blade capable of boosted applications. A high-performance, high-torque motor delivers quicker response over competitors weaker stock motors, while a dual return spring and a precision non-contact TPS increase reliability. The throttle body also features a stylish satin black anodized finish for excellent aesthetics and a unique look.
