Engineered for reliable heavy-duty diesel performance, the BOSCH 0445120255 Common Rail Diesel Fuel Injector belongs to the 120 Series CRIN family and delivers OE-style fitment for Dodge Ram 2500 and Ram 3500 pickups powered by the Cummins 5.9L diesel 6-cylinder engine. This electromagnetic common rail injector supports high-pressure diesel fuel metering and precision atomization under electronic ECU control, contributing to strong engine durability and emissions-oriented performance.
Designed as a direct replacement unit, this injector offers broad OE number coverage and easy part-number identification for procurement and service teams. It replaces 0445120018, 0445120113, 0445120210, and cross references OE numbers 5086894AA, 05086894AA, R8004082AC, 5263318, 5254686, 4940589, 3949619, and 3947550. Fitment must be verified by VIN, engine serial number, original injector number, and ECU calibration to ensure correct application.
For long service life, use clean diesel fuel, replace the fuel filter on time, drain the water separator if equipped, and use only approved diesel additives. During service, monitor rail pressure, perform injector return-flow testing, and inspect wiring and connectors. Common symptoms such as hard starting, rough idle, white or black smoke, and high fuel consumption should be diagnosed using rail-pressure testing, cylinder balance testing, DTC scanning, and professional test-bench verification.
