Grams Performance 70mm DBW Throttle Body 04-09 Audi A4 (B7) 2.0T 08-16 Audi A4 (B8) 2.0T Drive-By-Wire Electronic Throttle Body. The Plug-n-Play Electronic Throttle Body was designed to replace the restrictive factory unit for increased horsepower and throttle response. The Grams throttle body is a Plug-n-Play direct OEM replacement that does NOT require swapping electric motors, wiring, or mounting adapters. These units are not re-manufactured. Each throttle body includes all new components including a CNC machined billet 6061-T6 aluminum housing with a precision-honed oversized bore, a responsive high-torque servo motor, and a proprietary Non-Contact Hall Effect TPS sensor. To ensure the best performance, throttle response, and drive-ability, each TPS sensor is calibrated to meet the specific requirements of the vehicle’s engine management system. The Grams electronic throttle body is the perfect upgrade for both modified* and stock engines with increased airflow demands.
