FAQ

Q1: Is this injector a direct fit for my Cummins ISB engine?
A: This injector (0445120002) is compatible with many Cummins ISB, ISC, and ISL engines. However, due to variations in engine builds and years, we recommend verifying your engine serial number or comparing the physical injector to the original before purchase.
