These throttle body flange upgrade mounts at the throttle body, and is intended to mount a water/meth injection nozzle for detonation suppression, the flange also adds plenum volume (good for boosting midrange torque). This flange is a must have for those running a water/meth system. Use the flange to get your electronic throttle body out of harms way. Spraying directly at or near the electrical components will result in throttle body failure costing you hundreds of dollars. We have the throttle body flange solutions for 1.8t Audi, 1.8t VW/Audi TT, 2.0l FSI/TSI, 2.0l 8v MK3/4, VR6 OBD1, VR6 OBD2, R32 MK4, 2.5L MK5 Included with each flange comes with all necessary gaskets and bolts for install.
