TSP Silver 103 Electric Throttle Body with Swappable Flange

⚠️ IMPORTANT: This throttle body is only compatible with Gen IV LS engines using a 58x reluctor wheel. It will NOT work with Gen III 24x engines.

TSP 103mm DBW Throttle Bodies are CNC milled from billet aluminum, and their larger 103 mm inlets provide increased airflow for high-horsepower LSX platforms. The 103 mm throttle bodies require an aftermarket intake to fit the larger diameter blade. This requires engine calibration and is not a direct bolt-on for the OEM intake manifold.
