Over time, the factory high-pressure fuel pump (HPFP) seals in Audi 4.2L EA824 and 6.3L EA398 engines degrade, leading to fuel leaks, pressure loss, and performance inconsistencies. Additionally, upgrading to larger HPFP pistons—often used in high-performance applications—can cause the OEM seal to tear, resulting in fuel seepage and oil dilution inside the motor.
The TGK Motorsport HPFP Seal Rebuild Kit is designed to fix factory leaks, replace torn seals from HPFP upgrades, and restore fuel system integrity. Whether you're performing preventative maintenance or modifying your engine for more power, this kit ensures optimal HPFP operation and long-term reliability.
