Product Description
Radium Top Feed Fuel Rails (Top Port) For 02-14 Subaru WRX/STI
Description:
These fuel rails have the same mounting, injector spacing and fitment as the 20-0467-02 . However, each fuel rail has an 8AN ORB "top port", unlike 20-0467-02 which has a center lower port. The added clearance is necessary for the EJ207 and JDM EJ205 engines that have early AVCS solenoids with vertical connectors. 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. 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. The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85.
Included:
- Black Anodized Laser Etched Aluminum Fuel Rails (x 2)
- Phenolic Thermal Insulating Press-In Spacers, 20 mm (x 4)
- Phenolic Thermal Insulating Press-In Spacers, 15 mm (x 4)
- Stainless Steel M8 x 1.25 Mounting Bolts (x 4)
NOTE: Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.
