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.
Optional 8AN port for Selection for adding Dampers or Gauge Monitor.
