DBW Bosch 83 mm E-Throttle Adapter SpecificationsFirst introduced in the late 1980s electronic throttle control sometimes called drive-by-wire (DBW) uses electronic signals instead of a conventional mechanical link to control the throttle. This technology offers many advantages in terms of engine wear performance and efficiency.A DBW device is not only lighter (no throttle cable and fewer moving parts) but also provides idle control throttle response adjustment and a launch control function.Offered by our partner MZR Garage this adapter kit allows you to mount an 83 mm Bosch electronic throttle body (Audi 4.2 V8 OEM) on a custom intake manifold. It is delivered with the necessary hardware for the installation. The throttle body pedal harness and DBW compatible ECU are not included and must be purchased separately.Upgrade : The manufacturer is offering an upgrade with an additional part to perfect the connection with the intake duct and upgrade the V1 kit to V2.
