FAQ

Q: Will this injector fit my Cummins 6.7L engine without modification?
A: Yes, this is a direct OE replacement injector (Part #0445120059). It is designed to be a bolt-on replacement for the Cummins ISBe and QSB6.7 engines. However, we recommend comparing the injector code on your original part to ensure it matches the Bosch code listed (0445120059) before installation.

Q: Do I need to calibrate the injector after installation?
A: For optimal performance and to prevent engine damage, professional installation is required. The injector must be installed with new copper washers and hold-down bolts. After installation, the engine’s ECU should be programmed with the new injector’s IQA (Injector Quantity Adjustment) code, which is typically laser-engraved on the new injector.

Q: What is the typical lifespan of this injector in a heavy-duty application?
A: Lifespan varies based on fuel quality and maintenance. Under normal operating conditions with clean diesel and regular filter changes, these injectors can last between 150,000 to 250,000 miles. Poor fuel quality or water contamination can significantly reduce lifespan. We recommend using a fuel additive to lubricate the high-pressure pump and injectors.
