Radium Engineering Dual Port Injection Fuel Rails - Fits 02-14 Subaru WRX
These Radium dual port injection (DPI) fuel rails were designed specifically for the Radium fuel rail housings and are NOT compatible with any others on the market. The rails are manufactured with large 10AN ORB end ports. These fuel rails can support all necessary engine power requirements. The top auxiliary ports are threaded with 8AN ORB for ancillary accessories.
Primary Lower Fuel Injectors
Using the provided adapters, both OEM Subaru or 60mm Bosch EV14 style fuel injectors can be used. To reuse the OEM Subaru injectors, the provided top hat must be installed over the upper OEM injector O-ring.
Secondary Upper Fuel Injectors
Only 34mm Bosch EV14 style fuel injectors can be used. Fortunately, many Subaru owners are currently already using Injector Dynamics XXXX.48.11.WRX fuel injectors. If the upper and lower billet caps are pulled off, the base injector is a 34mm Bosch EV14 which can be used. Below are the compatible secondary upper injectors.
- CNC machined from solid 6061 aluminun
- Black anodized finish
- Laser engraved for a high quality surface finish
- Compatible with all fuel types including alcohol mixtures such as E85
