Audi S3 Fuel Pump – APR High Pressure Pump – Rebuild (2015–2020). Upgrade your factory Hitachi Gen III HPFP with APR’s precision‑machined internals for demanding S3 builds.
By increasing internal displacement, APR’s HPFP delivers 37% more fuel volume over stock, helping maintain commanded pressure with larger turbos or ethanol blends. Parts are heat‑treated, bearing‑grade stainless, machined to .00004 in/.00005 in tolerances; a DLC‑coated plunger and matched spring support reliable operation. Assembled in‑house and verified on a test rig. Note: this is a rebuild of your existing, working pump and solenoid; package carefully.
