Deliver metered fuel to the engine with the Standard Ignition Fuel Injector FJ23. It drops in as a direct-fit replacement for the 1981-1983 Nissan 280ZX, restoring the electrically controlled valve that sprays fuel into the intake so the engine can run on the correct air-fuel ratio.

  • Core function: An electronically actuated injector that opens on command from the engine management system to spray a metered charge of fuel, then closes to shut off flow.
  • Direct-fit replacement: Serves as a replacement injector for the listed 280ZX application.
  • Signs it may need replacing: Rough or uneven idle, misfire, hesitation, hard starting, or poor fuel economy can point to a leaking, clogged, or stuck injector. Diagnose the cause first — if a failed injector is behind the symptom, this replaces it.

Fuel injectors can wear or clog over time; replacing a faulty unit helps return the affected cylinder to proper fuel delivery.
