Engineered for demanding heavy-duty operation, the 3412 Series Fuel Injector 198-6877 delivers precision fuel atomization for V12 diesel powertrains rated between 425–605 HP and up to 625 HP in DITA and E variants. Cross-referenced with OE numbers 9W-8895 and 184-4412, this injector is a direct replacement solution for industrial, marine, construction, mining, and power generation applications where consistent combustion efficiency is critical.

Built from high-grade steel and alloy components, the injector features a multi-hole atomization nozzle with a 155° spray angle and an operating pressure range of 2000–2500 bar. Each unit is manufactured to OEM specifications for spray pattern, flow rate, and injection pressure, ensuring optimal fuel economy, reduced emissions, and stable performance across the full load range of the 18.1 L V12 platform. The direct-mount installation design simplifies replacement, while heat-resistant construction extends service life under continuous heavy-duty cycles. Global compliance with EPA and EU emissions standards makes this injector suitable for fleet operators, OEM rebuilders, and industrial maintenance contractors worldwide.

Recommended maintenance includes inspection every 500 operating hours, cleaning of nozzle tips with approved industrial solvents, periodic fuel system diagnostics to detect leaks or misfires, and replacement of seals and O-rings during routine service. Backed by a 12-month OEM quality warranty, the 198-6877 injector offers reliable long-term value for generators, marine engines, and heavy machinery fleets.
