Engineered as a direct fit for the Cummins N14 diesel platform, the 3083846 fuel injector delivers dependable performance across on-highway, industrial, and stationary power applications. Carrying primary OE reference 4323846 and cross numbers 3047963, 3411766, 3411767, 3411768, and 3411769, this component provides fleet operators and service centers with a reliable interchange solution for N14, N14 CELECT, N14 CELECT Plus, N14 STC, and Big Cam engine configurations.

Manufacturing integrity is central to this injector. High precision machining and CNC manufactured components are combined with a heat treated injector body, hardened internal parts, and corrosion resistant surface treatment. Industrial grade sealing technology and OEM specification calibration ensure consistent operation, while 100% flow, leak, and spray pattern testing verifies each unit before dispatch. The result is superior fuel atomization, stable injection timing, improved fuel economy, lower exhaust emissions, and reduced engine noise under sustained heavy loads.

This injector suits N14-310 through N14-525 HP engines and fits Freightliner, Kenworth, Peterbilt, International, and Western Star trucks, plus mining, marine, construction, agricultural, and power generation equipment. Recommended service practices include replacing sealing washers, lubricating O-rings with clean diesel fuel, tightening to Cummins specifications, and bleeding the fuel system before start-up. Routine fuel filter replacement and spray pattern inspection extend service life across extreme climate conditions.
