Radium Engineering - Fuel Rails, Top Feed Upgrade, Subaru EJ - 02-14 Subaru Impreza WRX STI
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 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.
NOTE: The center port bulge (shown above) can create an interfere with early AVCS solenoids found in the EJ207 and JDM EJ205. See 20-0479-02 below.
