103mm Drive-by-Wire Throttle Body

The Nick Williams 103mm throttle body serves as a high-performance upgrade for GM Gen 5 LTX engines. Each unit is CNC precision-machined from billet aluminum to provide the structural integrity and flow characteristics required for modified engines demanding higher air intake capacity. This drive-by-wire throttle body replaces the factory component to support increased engine output. Installation of larger-bore throttle bodies typically requires tuning of the vehicle's engine control module to ensure correct idle, transient throttle response, and overall drivability. Professional installation and calibration are recommended to integrate the unit correctly with the engine's existing electronics and air intake system.
