Nick Williams 112mm LS3/L92/LS7/LSXR (Electronic) Throttle Body, Will work on modified LS1/LS2/LS6 engines also. This throttle body accepts the LS2/LS3 stock throttle body harness. The 112mm 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. This throttle body has a 4.75" OD, so you'll want to use a 4.75" coupler. Comes in a natural billet aluminum finish.
NOTE: LS1 Vehicles require adapter harness. Harness allows the use of a LS2 throttle body on an LS1 vehicle.
