Radium Engineering Subaru EJ top feed fuel rail kit

Radium Engineering fuel rail conversion kit for Subaru EJ engines. The kit is used to convert from the original side feed injector setup to top feed injectors, allowing a wider range of performance and high-flow injectors to be fitted.

The fuel rails are CNC-machined from aluminium, black anodised and laser engraved. They are designed with a large internal bore and 14 millimeter injector ports, making them suitable for tuning, motorsport, E85 and upgraded fuel systems.

Each fuel rail has 3 8AN ORB ports, giving 6 ports in total. This provides a flexible setup for different fuel systems, regulator placements and hose routing. Insulating press-in spacers are also included, helping to reduce heat transfer from the intake manifold.

The kit includes:
Black anodised and laser-engraved aluminium fuel rails
Green anodised and laser-engraved 22 millimeter injector seats
Thermally insulating press-in spacers, 15 millimeter
Stainless mounting hardware
