Nick Williams 103mm drive-by-wire CNC billet throttle body for LS applications. This redesigned version replaces the previous 102mm boosted & non-boosted versions.
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 LS performance engines. The 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 completely assembled with bolts included.
**NOTE** Tuning is required for installation!
