The 034Motorsport High Pressure Fuel Pump Piston Upgrade Kit, 2.0TSI, 2.5TFSI, 3.0TFSI Supercharged is designed to be a drop-in replacement piston for the factory high pressure fuel pump for the Gen 2 EA888 2.0 TSI engines in the B8/B8.5 Audi A4/Allroad & A5, the 2.5 TFSI in the 8J Audi TTRS, and the EA837 3.0T TFSI Supercharged equipped B8/B8.5 Audi S4/ S5/Q5/SQ5 and C7 Audi A6/A7.

By upgrading the factory high pressure fuel pump with the 034Motorsport High Pressure Fuel Pump Piston Upgrade Kit, 2.0TSI, 2.5TFSI, 3.0TFSI Supercharged, the factory fueling limits are raised by up to 50% in 2.0T, 2.5T, or 3.0T 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!
