Good To Know

Q: Should injectors be replaced as a full set? A: Replacing all injectors together is often recommended when one fails, since matching wear keeps fuel delivery balanced across cylinders.

Q: Is coding or calibration required after installation? A: Some diesel engine management systems store injector trim codes, so check the service manual for your QSB6.7 or QSB5.9 application before installing.

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