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 2.9T and 3.0T TFSI EA839 engines found in the B9/B9.5 Audi S4/S5/SQ5/RS5, C8 Audi A6/A7/S6/S7, and 4M.5 Audi Q7/Q8.
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 37% in 2.9T or 3.0T EA839 engines. This increased flow allows the fuel system to meet the higher demands for ethanol, race gas, more pump gas, and pairs perfectly with all Dynamic+ ECU software that requires an upgraded High Pressure Fuel Pump!
