Radium Engineering Subaru 2001 - 2006 WRX/STI EJ-Series Engines Top Feed Fuel Rails (w/ Top Port)

Reference the chart below to be sure the proper fuel rails are ordered.

Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser etched for a high quality surface finish. 

These fuel rails are designed specifically for OEM or equivalent fitment injectors. For injector height flexibility and thermal insulation, 2 sets of machined insulating spacers are included. All injectors must use 11mm diameter upper O-rings just like the OEM Subaru injectors. Reference instruction manual for more information.

The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85.
