Audi A4 Fuel Pump – APR High Pressure Fuel Pump (2005–2008). Purpose-built for the 2.0T FSI, this upgrade increases pump displacement to deliver the fuel volume demanded by performance setups.

APR delivers a 41% gain over stock by enlarging the pressurizing cylinder, helping the system hold commanded rail pressure under heavy load and through the midrange. Internals are precision‑machined from bearing‑grade stainless with a DLC‑coated plunger. A matched spring and new seals are included, and each unit is rig‑tested. Uses genuine Hitachi pump bodies. Proper software is required; inspect/replace the cam follower.
