Radium Engineering's parallel fuel rail plumbing kit for Subaru EJ engines plumbs the rails in a parallel dead‑end layout and is compatible with 2008‑on Subaru Impreza/WRX/STi models. E85 compatible, it interfaces with Radium fuel rails and the factory feed and return while omitting an in‑kit fuel filter. The package provides the plumbing and fittings needed for a parallel dead‑end rail setup.
