Product Description

The Radium Engineering 20-0879 Fuel Rail is specifically engineered for the 3.2 L 24-Valve VR6 engine found in select Volkswagen, Audi and Porsche models (2001-10). Featuring a large internal bore and billet aluminium construction, this fuel rail delivers high-flow capability required in performance or modified builds. The design retains the OEM injector bore size, making it compatible with existing injectors while providing superior fuel delivery capacity and pressure stability.

Installation is straightforward with the included hardware and thermal spacer kit. The rail bolts into the factory mounting points and integrates with modern 8 AN ORB plumbing for fuel feed and return. Suitable for tuned or stock applications alike, the 20-0879 fuel rail is an ideal foundation for high-performance VR6 builds requiring reliable and scalable fuel system upgrades.
