Radium Fuel Rail Without Fittings 2001-2006 BMW M3 E46 2001-02 Z3 M 06-08 Z4 M S54B32

This basic kit includes only the fuel rail and mounting hardware. This is ideal when plumbing a custom high flow fuel system using an aftermarket regulator and custom fuel lines. Fittings and adapters are available separately.

This big bore fuel rail is machined, polished, laser etched and then anodized for a stealth surface finish. It is compatible with OEM and aftermarket direct fitment fuel injectors. It features a large 0.65" internal bore with -8AN ORB (3/4-16 O-ring) threaded ports at each end and 3/8" NPT female center port to accept a variety of adapter fittings for custom high flow fuel system builds. It is compatible with all fuel types including popular alcohol mixtures such as E85. The fuel rail is a direct bolt-on for all BMW's equipped with the S54 engine.
