JHM Fuel Filter – High Volume for B6 A4 1.8t (all) and late (04-05) 3.0l V6, B6 S4 and EARLY B7 S4 w 4-lines

JH Motorsports is pleased to now offer our NEW High Flow Fuel Filter for the B6 A4-S4 and EARLY B7-S4!

For years there has been a lack of complete aftermarket fuel pump kits due to the factory fuel filter regulator assembly not being able to regulate the high volume of fuel that upgraded pumps provide. This is why we include our JHM Specific – High Volume Fuel Filter with our JHM Fuel Pump Upgrade Kits. NOTE: If you are looking to purchase our complete fuel pump kit, please go back one section.

The issue with factory and replacement fuel filters is that the fuel regulator is not able to accept the high volume of fuel when at low speeds and at idle when the car isn’t using as much fuel (as apposed to WOT) and the fuel pressures rise above the regulator specifications causing the fuel to not be able to return to the tank fast enough. This can cause fuel trim and other fuel related issues. Our High Flow Fuel Filter has a redesigned regulator to prevent these issues from occurring.
