Radium Engineering Top Feed Fuel Rail Upgrade | 2002-2014 Subaru WRX, 2004-2021 Subaru WRX STI, and 2006-2012 Subaru Legacy GT (20-0577-02)

Multiple Subaru Fitments Top Feed Fuel Rail Upgrade by Radium Engineering

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.

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.
