Audi S5 Fuel Pump – APR – High Pressure Fuel Pumps – Rebuilds – 08–12. This service upgrades your factory HPFP with APR internals to increase fuel volume on 2008–2012 S5 models.

By enlarging the pressurizing bore, displacement rises 41% over stock to help the system hold commanded pressure in demanding, higher‑output use. Rebuilt in a clean environment with heat‑treated, bearing‑grade stainless parts, it includes a DLC‑coated plunger, weight‑matched spring, and new seals. The factory pivoting head is retained to limit cam‑follower wear. Each unit is assembled and tested in‑house. Requires sending your working pump and solenoid.
