The Granatelli Throttle Body Adapter Plate is intended for 2013-2024 GM LS. The supplied catalog describes this part as LS Series Adapter Plate with Hardware. Allows for LS 112mm Throttle Body To Be Installed on Stock LS Bolt Pattern manifolds with out requiring porting. 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.
