5-Bar Fuel Pressure Regulator
Check to see if your vehicle is compatible
This part fits these vehicles:
- Audi A4 B5 1.8T FWD
- Audi A4 B5 1.8T quattro
- Volkswagen Passat B5 1.8T
If you have a 1 bar or higher chip in your 1997-99 A4 1.8T or 1998-99 Passat 1.8T, our 5-bar fuel pressure regulator will give you the extra fuel delivery you need for high RPM/load operation. We modify a new regulator to increase the line pressure.
Recommended for vehicles that see sustained high speed/high RPM conditions.
