Deliver a precise, metered spray of fuel with the Standard Ignition Fuel Injector FJ121. This electronically actuated injector is a direct-fit replacement for the listed applications: the 1991 Eagle Vista; 1991-1992 Dodge Colt, Plymouth Colt, and Mitsubishi Mirage; 1991-1994 Eagle Summit; and 1995-2000 Chrysler Cirrus, Chrysler Sebring, Dodge Avenger, and Dodge Stratus.

  • Electronically controlled valve: opens when the engine control module energizes it and closes to stop fuel flow.
  • Atomized delivery: sprays a measured charge of fuel for combustion.
  • Sold individually: most engines use one injector per cylinder, so order the quantity your application requires.

A fuel injector is an electronically actuated valve: on the ECU's signal it opens to inject a measured charge of fuel, then closes. If a clogged, leaking, or stuck injector is behind rough idle, hard starting, misfires, hesitation, or poor fuel economy, this replaces the faulty unit. Diagnose the fuel system to confirm the injector is at fault before replacing.
