Keep fuel metering crisp with the Hitachi Astemo Fuel Injector FIJ0039, a direct-fit replacement for the 2014-2015 Subaru Forester and the 2015 Subaru WRX. A fuel injector receives commands from the engine's control module and delivers a precisely metered, atomized spray of fuel for combustion, so a clean spray pattern and accurate flow are central to smooth, efficient running.

  • Precise fuel delivery: meters and atomizes fuel on command for consistent combustion.
  • Direct-fit application: engineered to drop in on the listed Subaru applications.
  • Signs this part may need replacing: rough idle, misfire, hesitation, hard starting, or poor fuel economy — if a failed injector is the cause, this replaces it.

Because these symptoms can have other causes, diagnose the source before replacing. If your engine uses multiple injectors, confirm how many your application requires before ordering.
