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 LSX performance engines. The 102mm 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. These systems can add serious power over your stock or even ported 90Mmm systems especially in boosted applications. Pair one up with an aftermarket intake for biggest gains.
