Radium's Subaru Top-Feed Fuel Rail Upgrade Rail Kit is a perfect bolt-in option for Boxer engines designed with factory top-feed injectors. Different height injectors (sold separately) can be used by swapping out the included insulating mounting boss spacers.

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 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 20-0479-02.

However, these fuel rails feature a 8AN ORB port machined in the underside center of each fuel rail.

NOTE: The center port bulge can create an interfere with early AVCS solenoids found in the EJ207 and JDM EJ205. If this is the case, use P/N: 20-0479-02.

  • Black Anodized Laser Etched Aluminum Fuel Rails (x2)
  • Phenolic Thermal Insulating Press-In Spacers, 20mm (x4)
  • Phenolic Thermal Insulating Press-In Spacers, 15mm (x4)
