The 034Motorsport High Pressure Fuel Pump Piston Upgrade Kit is designed to be a drop-in replacement piston for the factory high pressure fuel pump for the 2.0 FSI engines in the B7 Audi A4, 8J Audi TT/TTS, Mk5 Volkswagen GTI/GLI/EOS, B6 Volkswagen Passat, and Mk6 Volkswagen Golf R.

By upgrading the factory high pressure fuel pump with the 034Motorsport High Pressure Fuel Pump Piston Upgrade Kit, the factory fueling limits are raised by up to 50% in the 2.0T FSI engine. This increased flow allows the fuel system to meet the higher demands for ethanol or more pump gas, and pairs perfectly with all Dynamic+ ECU software that requires an upgraded High Pressure Fuel Pump!
