Audi RS4 Fuel Rail Return Valve / Pressure-Relief Valve - Stage 2.5 EA113. 140 BAR Genuine Volkswagen / Audi product. Part number: 079130757 Use this for stage 2.5 tuning with HPFP upgrades on EA113 etc or if you are going stage 3! Strongly recommended to use with HPFP insert / upgrade.

This Part is a great upgrade from your stock 2.0T pressure regulator valve which has an opening pressure of 130bar. With an opening pressure of 140bar you will be able to delivery more fuel to your 2.0T FSI engine giving the ability to make more horsepower. Recommended to bundle: 06J906051D Pressure Relief Valve. This valve determines the pressure in the fuel rail. The 'cracking pressure' of your fuel rail return valve is the point at which the valve opens and allows fuel to exit the fuel rail. Because this valve has a higher cracking pressure than the standard 2.0T valve, you will get a higher rail pressure and therefore more fuel in the fuel rail. More fuel means more power. This is a great upgrade for your fuel system as it will work with the standard injectors and also with upgraded injector and HPFPs. You should also consider upgrading your fuel pressure sensor so it can accurately read the higher rail pressure - part number 06J906051D - we also have this part.

This product is designed for use in conjunction with appropriate supporting hardware and ECU calibration. Installation of this component without proper tuning may result in unintended changes to fuel system behaviour, including but not limited to fluctuations in fuel pressure, air-fuel ratio inconsistencies, hesitation, surging, or engine misfires. For optimal performance and reliability, it is strongly recommended that this upgrade be used only with a calibration specifically designed to support higher fuel rail pressure. This product is not a standalone performance upgrade. It does not directly increase power output and should be considered a supporting modification for higher performance applications. Results will vary depending on vehicle condition, supporting modifications, and tuning quality. By installing this component, the user acknowledges that: Professional installation is recommended Appropriate ECU tuning may be required Regular maintenance of ignition and fueling components is essential Use of this product may increase mechanical stress on engine and fuel system components VAGPARTS Australia recommends genuine parts.
