The Granatelli Throttle Body is intended for 2008-2023 GM LS3. The supplied catalog describes this part as GM Drive-By-Wire LS3/LSA/LSx Throttle Body 108MM - Drive-By-Wire- Natural. The year range should be read as the applicable engine/platform generation rather than as guaranteed fitment for every vehicle built during those years. Granatelli states its drive-by-wire throttle-body line is designed as a direct-replacement performance upgrade and can increase airflow depending on the application, supporting improved throttle response on compatible combinations.
Fitment Note: This row is treated primarily as engine/platform applicability. Confirm the exact engine code, ignition or accessory configuration, and vehicle-specific clearance before ordering.
