Common-rail injector, replacement for BOSCH 0445120121, used on Cummins ISLe 8.9L engines (ISLe / ISL / ISC). The injector is matched to the original Bosch number so it seals against the existing copper washer seat and locks into the OEM clamp.
We supply this part as a component with our installation and commissioning guide. Correct fitting (clean fuel circuit, a new copper washer, the OEM clamp torque, and coding to the ECU where applicable) is essential for reliability, so we recommend following the guide and confirming fitment by Bosch code before ordering.
Send your Bosch number and engine model (or a photo of the injector and its label) and we confirm compatibility.
