Description

Raise the factory high-pressure fuel system’s capacity on C7 Audi 4.0T applications with TGK Motorsport’s precision-machined piston upgrade. The larger piston is intended for builds that need more fuel volume for ethanol blends, race fuel, or optimized pump-gas calibrations.

Key details

11.65 mm piston diameter versus the 9.98 mm factory piston.
Approximately 36.27% more calculated flow area than stock.
Hardened tool-steel piston with a low-friction DLC coating.
Includes two pistons, two seals, two tappets/cam rollers, and the installation tool.

Application: Supplier-listed for C7 S6, S7, RS6, and RS7 4.0T models. High-pressure fuel-system work requires exact installation; professional installation and tune review are recommended.
