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. Tuning is required for installation; and 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.
LSx Surge Intake
Our unique design based on Holley's proven HiRam manifold provides unmatched power and torque production for a manifold in this compact of a package. Designed specifically for boosted engines the dual plenum intake excels in perfect air distribution across the engine. Insuring that each cylinder is reaching it's full potential to maximize engine efficiency and output. Measuring just under 9-7/8" from the valley flange of the block this provides an additional 3" of hood clearance versus the standard Hi-Ram configuration.
