Audi S5 Fuel Pump - APR High Pressure Fuel Pump (2018-2024). This complete HPFP upgrade increases available fuel volume for the EA839 3.0T, helping your S5 hold commanded rail pressure under heavy load and with higher-demand calibrations.
By increasing the pump’s displacement, APR delivers more volume without chasing higher rail pressure. Bearing-grade, heat-treated stainless internals with a DLC-coated plunger run at 0.00004–0.00005 in tolerances, matched to a properly specified spring and titanium retainer. Genuine Hitachi critical components are used throughout. Each pump is assembled in-house, machine-tested, and broken in. Compatible ECU software is required.
