Full Description:
Manufactured with a large internal bore, the Radium 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 phenolic 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.
These fuel rails have the same mounting and injector spacing as the 20-479-02 (below). However, these fuel rails feature a 8AN ORB port machined in the underside center of each fuel rail.
Install Notes:
The center port bulge (shown above) can create an interference with early AVCS solenoids found in the EJ207 and JDM EJ205. Check out the Top Feed Upgrade with -8AN Top Port fuel rails if you have this issue.
