034Motorsport Audi 4.0T High-Pressure Fuel Pump Piston Upgrade Kit

The 034Motorsport High-Pressure Fuel Pump Piston Upgrade Kit is designed to be a drop-in replacement piston for the factory high-pressure fuel pumps for the Audi 4.0T engine in the C7 Audi S6/S7/RS6/RS7.

By upgrading the factory high-pressure fuel pumps with the 034Motorsport High-Pressure Fuel Pump Piston Upgrade Kit, the factory fueling limits are raised by up to 50% in the Audi 4.0T engine. This increased flow allows the fuel system to meet the higher demands for ethanol, race gas, more pump gas!
