The Audi S6 Fuel Pump - APR - High Pressure Fuel Pump - `18-`24 is a precision-engineered direct-replacement HPFP for the EA839 S6. By increasing the pump’s displacement, it delivers greater fuel volume to help keep rail pressure steady under heavy load, larger turbos, and ethanol blends.
APR machines the plunger and barrel from heat-treated bearing-grade stainless and applies a DLC coating to the plunger for durability. Components are built to extreme tolerances in a clean environment, then assembled in-house using a new OEM Hitachi pump body and sensors. Each unit is bench tested, supplied with a weight-matched spring, and fitted with new seals. Expect dependable fueling headroom—up to a 37% increase in displaced volume versus stock—with OEM-like drivability. Compatible ECU software is required.
