Boomba 75mm DBW Throttle Body- Bolt On

Boomba Racing noticed the factory throttle body was lacking, and improvements could be made. Starting with billet aluminum, this throttle body is a direct replacement for your stock DBW unit. It can accept a 60mm hose with the included adaptor plate, or a 75mm hose for the higher boost applications.

This throttle body is designed to use your stock TPS and servo motor. Please make sure that you have the BOLT ON unit from the factory, as it is not compatible with the snap on version throttle bodies.
