Specs At A Glance

Good To Know

Q: Should all six injectors be replaced at once? A: Replacing the full set keeps fuel delivery balanced across all cylinders and avoids mismatched wear between old and new units.

Q: Is any programming required after installation? A: Many modern diesel injectors need calibration or coding to the engine control module, so confirm the procedure for your machine before install.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
