95mm LT5 Throttle Body

The Genuine GM 12740728 LT5 95mm Throttle Body is a direct-replacement, OEM component originally used on the 2019 Corvette ZR1. This throttle body is a favored upgrade for those seeking enhanced airflow on Gen V LT engines, including LT1, L86, and LT2 applications, when paired with the necessary adapter plate and supporting modifications. Constructed to stringent GM original equipment standards, this 95mm throttle body ensures the quality, precise fit, and reliable electronics expected from a factory part. This throttle body is particularly noted as a popular conversion part for LT1, L86, LT2, and other Gen V LT-based engine setups. When the correct adapter plate is installed, it provides a factory GM solution for stepping up from smaller throttle body configurations. It is ideal for a wide range of applications, including street performance, naturally aspirated setups, boosted engines, LT engine swaps, and custom intake projects. Important installation notes specify that tuning is required when using this throttle body on LT4, LT1, and L86 engines. Additionally, an adapter plate is necessary for it to bolt onto any standard LTx intake or supercharger. The part number 12669871 is a previous iteration, and this unit may arrive with the superseded part number 12740728 depending on current GM inventory; they are the same throttle body.
