Bar-Tek 4.0L TFSI Upgrade High Pressure Pumps are an upgrade for the high-pressure fuel pumps in Audi RS6 C7 and Audi RS7 C7 models equipped with the 4.0 TFSI engine. The product is designed for situations where the capacity of the original high-pressure pumps is no longer sufficient to support increased power levels and fuel demand.

The upgrade is based on Bar-Tek's defined pump solution, where the internal structure of the pump is dimensioned for greater flow capacity and higher rotational speeds, while maintaining compatibility with the engine's original fuel system.

Technical Specifications

• Flow Capacity: Approximately 50% greater compared to standard high-pressure pumps

• Piston Diameter: 11.5 mm (standard 10.0 mm)

• Tested RPM: Up to 8500 rpm

• Surface Treatment: DLC-coated piston and contact surfaces to reduce wear and friction

• Construction: OEM-type construction, compatible with the original system
