The Chevrolet Performance 12740728 is a Genuine GM LT5 95mm throttle body, originally part number 12669871 and superseded to 12740728. This is the factory-installed OEM throttle body for the 2019 Corvette ZR1 LT5 engine, offering a 95mm opening for increased airflow potential. It's a popular choice for builders aiming to enhance induction systems on Gen V LT1, L86, LT2, and other LT-based engines, whether for street performance, naturally aspirated setups, boosted applications, or LT engine swaps. Constructed to GM OEM standards, this throttle body ensures the quality, fit, and reliability expected from a genuine factory component. It provides a calibration-friendly foundation, making it suitable for those who prioritize proven factory parts over aftermarket alternatives for their performance builds. Installation of this LT5 throttle body requires specific supporting components. An adapter plate is necessary when installing this throttle body on LT1, L86, LT2, and other compatible Gen V LT-based upgrade applications to ensure proper fitment onto standard LTx intakes or superchargers. Furthermore, tuning is explicitly required when using this throttle body on LT4, LT1, and L86 engines to optimize performance and ensure correct operation.
