Nick Williams Performance Drive-By-Wire Throttle Bodies

Nick Williams Performance drive-by-wire throttle bodies are precision CNC-machined from billet aluminum to meet the demands for increased airflow on the drive-by-wire LSX and LTX performance engines. These 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. There is no need to disassemble your factory throttle body. Order the model designed for your vehicle and engine application.

Edelbrock Super Victor Intake Manifolds

Edelbrock Super Victor intake manifolds are arguably the most popular and flexible manifolds in racing today. You'll find these single-plane manifolds on oval tracks, in drag racing, and on NASCAR engines--anywhere that maximum horsepower and torque are needed. The extended, constant cross-sectional area of the runners produces more torque across the midrange--from 3,500 up to 8,500 rpm in most instances. So, they deliver great throttle response off of the corners in oval track racing and improved 60 ft. times in drag racing. Their direct "line-of-sight" flow path provides maximum flow and there's plenty of material for port matching. They're also ideal for alcohol use.
