Bosch original Common Rail Diesel Injector for ISB6.7 QSB6.7 Engine, 0445120332, Cross Reference 0445120185, Replacement for 0445120336, 0445120050, High Pressure Common Rail original new injector

Built for modern high-pressure common rail systems, the brand-new BOSCH 0445120332 electronic solenoid injector provides precise fuel metering and optimized atomization. ECU signals actuate the solenoid and injector needle, enabling pilot, main and post injection for controlled diesel combustion. The process supports improved fuel economy, reduced emissions, increased engine power, lower noise and better cold-start performance. Precision nozzle technology, corrosion resistance, heat resistance and Bosch OE manufacturing standards contribute to industrial durability and long service life.

Compatibility covers Cummins ISB 6.7L, QSB 6.7L, B6.7, ISDe Series and Cummins industrial common rail engines. Listed equipment appliions include heavy- and medium-duty trucks, commercial buses, construction and mining machinery, diesel generators, agricultural equipment and marine auxiliary diesel engines. Bosch OE references are 0445120332 and 0 445 120 332, with Cummins OE number 5262128. Cross references are supplied in the product table; verify them against engine calibration codes and injector flow specifiions before installation.

For distributors, rebuilders, workshops and fleet maintenance providers, the injector offers an OE-identified solution for commercial vehicle and industrial engine service. During installation, clean the injector seat, replace the copper washer and O-rings, verify rail pressure, perform coding if required, and conduct a leak-off test. Clean fuel, OEM-quality filters, periodic bench testing and fault-code monitoring support preventive maintenance.
