Radium Fuel Rail Mitsubishi Evo 4-9

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

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

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 three ports use -8AN ORB threads.
