Bosch original Common Rail Fuel Injector 109962-0042 Fuel Injector Nozzle for GE13 Engine Excavator Parts 0414701033 16650-00Z07 original new injector

Engineered specifically for the GM Duramax 6.6L V8 diesel platform, the Bosch GE13 common rail injector 0445120042 delivers a precise mechanical and electronic match for LBZ, LLY, and LMM engine calibrations. Built to Bosch OE standards with micron-level machining tolerance and precision matched internal components, this injector supports multiple injection events including pilot, main, and post injection to ensure precise fuel atomization, optimized combustion efficiency, and reduced particulate emissions across the full operating range.

This high pressure common rail unit supports modern injection systems operating up to 1600-2200 Bar depending on engine calibration, maintaining stable delivery under demanding duty cycles. A hardened alloy steel body, wear resistant needle assembly, and corrosion resistant coatings provide extended service life for both on-highway trucks and heavy industrial diesel equipment. Improved atomization contributes to better combustion, reduced fuel consumption, and enhanced engine power output for fleet and commercial operators.

Cross-referenced to 109962-0042, 0986435521, 0986435521RX, 97361355, 97780474, 5745888, 8-97361-355-6, AP55521, FJ962, and 732-503, it fits Chevrolet Silverado, GMC Sierra, Express, Savana, Kodiak, TopKick, and Hummer H1 applications, plus generator, mining, construction, agricultural, and marine auxiliary systems. Before installation, verify injector bore condition, fuel rail pressure, and seat cleanliness, install new copper washers and O-rings, and perform injector coding or adaptation where ECM calibration requires.
