Overview

The Nick Williams SD112LTX is a 112mm electronic drive-by-wire throttle body designed for LTX performance engines. It is precision CNC-machined from billet aluminum and features a natural finish. This throttle body requires an aftermarket intake manifold or adapter plate due to its larger throttle blade diameter.
Show original supplier description
The Nick Williams 112mm Throttle Body is precision CNC-machined from billet aluminum to meet the demands for increased airflow on drive-by-wire LTX performance engines. Featuring a 112mm venturi diameter, this throttle body utilizes a 6-pin late model connector compatible with contemporary wiring harnesses. It comes completely assembled with mounting hardware included. Installation requires an aftermarket intake manifold or adapter plate due to the larger throttle blade diameter; it will not fit factory intake manifolds. For LT4 superchargers, porting of the inlet is necessary for proper fitment. If used with an LT5 supercharger, an adapter plate is required, along with additional porting on the blower snout. Crucially, tuning is required for installation and optimal performance. This product is not CARB legal and cannot be shipped to California due to emissions restrictions. It is intended for use on uncontrolled (non-emissions controlled) vehicles or racing vehicles.
