82 mm Upgraded Throttle Body for Drag intake manifold EA888.3 EA888.4

Bosch Electronic Throttle Body (82 mm) The Bosch Electronic Throttle Body (82 mm) is designed for high-performance and motorsport applications where increased airflow is required beyond the limits of the factory throttle body. With its large 82 mm bore, it is an ideal choice for high-horsepower engine builds equipped with large turbochargers, providing the airflow needed to support maximum performance. This throttle body is fully compatible with the RTMG Performance Drag Billet Intake Manifold for VW/Audi EA888 Gen3 & Gen4 engines. Important: The Bosch 82mm throttle body is not compatible with the factory OEM ECU. Proper operation requires a standalone engine management system (ECU) with appropriate throttle calibration.
