Audi S4 Fuel Pump - APR - High Pressure Fuel Pump - 2018–2024. A robust HPFP upgrade that increases fueling capacity for the EA839 3.0T.
By increasing the pump’s displacement, this unit delivers 37% more volume than stock, helping maintain rail pressure under higher load, larger turbos, or ethanol blends. It’s built with heat-treated bearing-grade stainless, a DLC-coated plunger, and ultra-tight tolerances (as tight as 0.00004"/0.00005"). APR integrates genuine Hitachi components, replaces critical seals, includes a weight-matched spring, and machine-tests every pump prior to shipment. Compatible ECU software is required.
