For DI engines.
Nick Williams Performance drive-by-wire throttle bodies are CNC precision-machined from billet aluminum to meet the demands for increased airflow on the drive-by-wire LTX performance engines. The redesigned 103mm throttle bodies require an aftermarket intake to fit the larger diameter throttle blade. They use a 6-pin late model connector that works with late model wiring harnesses. The Nick Williams Performance drive-by-wire throttle bodies come complete with stepper motor and electronics installed—no need to disassemble your factory throttle body. Tuning is required for installation.
