Product Overview

An injector with poor spray pattern or leakage can cause hard starting, misfire, smoke, engine knock and uneven cylinder contribution.

Injector condition directly affects combustion quality. Before replacement, it is good practice to confirm fuel quality, injection-pump condition and compression so a new injector is not used to mask another engine problem.

Key Features & Performance

  • Meters and atomizes diesel fuel into the combustion chamber
  • Correct injector condition supports clean starting, balanced combustion and normal power
  • Intended for the listed engine/injector family; calibration and engine build must match
