original Factory Price Auto Parts Common Rail Diesel Engine Fuel Injector 3920214 392-0214 for C3500 Engine original new injector

Engineered for uncompromising performance in the world's most demanding diesel platforms, the 392-0214 Electronic Unit Injector delivers precision fuel metering and superior atomization for 3512B, 3512C, 3508B, 3508C, 3516B, and 3516C industrial engines. This heavy-duty injector assembly is designed as a direct replacement solution, fully cross-referenced with 20R-1275, 11R-0285, 10R-1290, 0R-8892, 0R-8690, 114-6469, 126-7995, 132-0204, 150-4456, 229-0193, 250-1314, and 386-1766, giving fleet operators, remanufacturers, and OEM aftermarket suppliers complete interchange coverage.

Manufactured from high-strength hardened steel alloys with precision-machined multi-hole nozzles, the injector produces consistent droplet size and spray patterns that maximize combustion efficiency and reduce particulate emissions. OEM and reman calibration includes trim codes tailored for each engine's ECM response, ensuring accurate fuel delivery under variable load conditions. Its corrosion-resistant design withstands harsh marine and offshore environments, while the robust construction supports continuous operation across power generation sets, mining trucks, drilling rigs, commercial vessels, and heavy construction equipment.

Routine service includes inspecting injector tips every 500 operating hours, replacing O-rings and high-pressure seals during rebuilds, and using sub-10 micron filtration to prevent nozzle clogging. Installation requires proper bore cleaning, seal lubrication, hold-down torque of approximately 70–90 Nm, fuel system priming, and ECU calibration where applicable. Backed by a 12-month warranty (extendable 12–24 months through OEM or reman suppliers), this injector delivers proven reliability for critical industrial applications.
