Bosch 0445120256 Common Rail Fuel Injector for Cummins

1. Product Overview

Brand new Bosch 0445120256 common rail fuel injector (type CRIN1-14/16, 1600 bar) for Cummins engines. The OE number 5263319 and the exchange number 0986435576 both rest on a single technical-file source and are marked to be confirmed; the same file names the Cummins application without fixing a specific engine model, so the exact engine fitment is to be confirmed by engraving or VIN. Family warning: this injector shares its nozzle (0433172200) and control valve (F00RJ02130) with 0445120239, but the OE and application records differ — the two are NOT interchangeable. It also belongs to the Cummins 526331x OE segment together with 0250 / 0251 / 0252, whose OE numbers differ in the last digit only — never cross-order between them.
