Cummins 2872405 Fuel Injector Assembly

The Cummins 2872405 is a high-pressure common rail XPI fuel injector designed for 15.0L ISX15, QSX15, and X15 engine platforms. It utilizes solenoid-actuated pressure-assisted injection technology to achieve injection pressures exceeding 1800 bar, enabling multiple injection events per cycle for optimized combustion, reduced emissions, and improved fuel economy. This injector assembly features a bolt-on mounting style with a black electrical connector. It is calibrated for EPA10 and EPA13 emissions standards and compatible with CM2250 and CM2350 engine control modules. The nozzle assembly (typically referencing 4984805) is engineered for precise spray pattern and atomization. Units are available as new OEM, genuine remanufactured (replacing all wearable components with OE Bosch or equivalent parts), or aftermarket replacement. Professional installation and calibration verification via engine serial number (ESN) and CPL are recommended.
