Radium Engineering Fuel Rail BMW M3 (E46 S54)

Radium Engineering Fuel Rail - BMW M3 (E46 S54)

This Radium Engineering fuel rail is built for owners putting together a custom high-performance fuel system on the BMW E46 M3 with the S54 engine. It is CNC machined from 6063 aluminium, black anodised with laser-etched branding, and suits all fuel types including E85 and other ethanol blends.

This listing is for the fuel rail only – no fittings, hoses or adapters are included – making it a good base for setups using an external regulator and custom plumbing. The 14mm injector bores accept OEM and equivalent injectors, with provision for the OEM injector retaining clips.

Note: Feed/return fittings, a centre-port plug or fitting, pulse damper, regulator and gauge adapters are sold separately. Check clearance when choosing fittings and accessories – the centre port only accepts one style of fuel pulse damper (Radium 14-0128). Installation by a professional is recommended.
