Radium Top Feed Upgrade Fuel Rails:
Note: Fuel Pulse Dampener (FPD) Not Included
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 Radium 20-0479-02 Top Feed Rails. However, these fuel rails feature a 8AN ORB port machined in the underside center of each fuel rail.
NOTE: The centre port bulge can create an interfere with early AVCS solenoids with the vertical connector (pictured above) found in the EJ207 and 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)
- Stainless Steel M8x1.25 Mounting Bolts (x4)
The fuel rail ports are tapped for 8AN ORB but fittings are not included.
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.
Injector Dynamics ID1050X:
The ID1050x is the evolution of the ID1000, and the latest addition to the X-Series. It is the most recent offering from the partnership of Injector Dynamics and Bosch Motorsport, and is the result of lessons learned during development of the ID1300x, and ID1700x. Like the ID1300x and ID1700x, the ID1050x is not a modified production component. It is a built to spec motorsport injector, offering optimization of critical operating parameters important to you, the motorsport tuner. Compared to the original ID1000, the ID1050x offers numerous improvements, and is sure to become the new reference. Corrosion resistant internals make it compatible with all known fuels, capable of extended service life with corrosive fuels. Compact body allows fitment in 200+ applications, including current and future engines utilizing short body injectors. Improved internal flow path increases output by 5% without sacrificing low flow performance. Stronger magnetic circuit offers stable operation up to 10 bar. Replaceable inlet filter extends service life. To learn more about the nature and development of the X-Series injectors, follow this link.
