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. The Radium fuel rail eliminates the OEM 2-bolt inlet flange which uses a restrictive 0.22" (5.7mm) orifice. All four ports use -8AN ORB threads. The fuel rail reuses the 3 OEM mounting spacers (Mitsubishi MD095402) to thermally insulate the fuel rail from the intake manifold. Furthermore, thermal insulating washers are provided for the stainless steel mounting hardware. Mounting bosses mimic the factory fuel rail for securing the cable(s) that pass by with the OEM brackets.  FUEL INJECTOR COMPATIBILITY 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’. 20-0533-02 Fuel Rail, Mitsubishi, Early 4G63This option includes only the basic fuel rail as shown in the picture below.
