Radium Fuel Rail Mitsubishi Evo 4-9

The fuel rail features three threaded ports that are all tapped for 8AN ORB

The Radium fuel rail eliminates the OEM 2 bolt inlet flange which uses a restrictive 0.22" (5.7mm) orifice. All three ports use -8AN ORB threads. 

Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements 

The rail is CNC machined from solid 6061 aluminum, anodized and laser etched for a high quality surface finish

It is compatible with all fuel types including popular alcohol mixtures such as E85.

This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.
