Radium Top Feed Fuel Rails Upgrade w/ Top Port JDM/EDM WRX 01-06 JDM WRX STI 01-02 EDM WRX STI 01-06

Depending on the vehicle's country of origin, this fuel rail kit is compatible with the following Subaru models:

2001-2006 Impreza WRX (JDM)
2001-2006 Impreza WRX (EDM)

2001-2002 Impreza WRX STi (JDM)
2001-2006 Impreza WRX STi (EDM)

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.

These fuel rails have the same mounting, injector spacing and fitment as the 20-0567-02 (above). However, each fuel rail has an 8AN ORB "top port", unlike 20-0567-02 which has a center lower port (picture below shown with Fuel Rail Adapter 20-0372).


The added clearance is necessary for the EJ207 and JDM EJ205 engines that have early AVCS solenoids with vertical connectors.

Included:
-Black Anodized Laser Etched Aluminum Fuel Rails (x2)
-Thermal Insulating Press-In Spacers, 20mm (x4)
-Stainless Steel M8x1.25 Mounting Bolts (x4)
