Good To Know

Q: Can I replace just one injector? A: It is possible, but replacing injectors as a matched set is often recommended when mileage is high. Inspect the remaining injectors before deciding.

Q: Is coding or programming required after install? A: Many modern common rail injectors require calibration coding to the ECU. Confirm the procedure for your specific engine before installation.

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