Aftermarket fuel-rail pressure-relief valve set to crack around 165 bar. Factory EA113 valves open nearer 120–130 bar; the RS4 079130757 is about 140 bar. This one is for higher commanded rail pressure on big-turbo EA113 / similar TFSI rails.
- Crack pressure: 165 bar
- Fitment: 2.0 TFSI rail (same family as the RS4 valve)
- Typical use: Stage 3, TTE-style hybrids, when the HPFP and file actually ask for the extra pressure
- Needs: upgraded HPFP internals and a file. Fitting it alone does nothing useful
