original 212-3464 Diesel Fuel Injector Assembly for C10 C12 3176 3196 NT855 Engine Excavator Loader Bulldozer Truck Replacement for OEM 10R-0967 161-1785 original new injector

Engineered for demanding diesel powertrains, the 212-3464 Electronic Unit Injector is a heavy-duty fuel injection component designed as a direct OEM-equivalent replacement for the C12 inline 6-cylinder engine platform. Cross-referenced as 2123464, this injector installs at the cylinder head position and serves 11.9-liter turbocharged, water-cooled engines operating within the 355HP to 505HP power range, including on-highway truck engines, industrial power units, marine propulsion systems, and generator set applications.

The 212-3464 features precision nozzle technology, hardened internal components, an advanced solenoid design, and corrosion-resistant materials engineered to withstand high-pressure operation. Each unit is manufactured to OEM flow calibration standards and factory tested to deliver precise fuel metering, improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, increased engine output, and sharper throttle response. Its heavy-duty industrial construction ensures reliable service in transportation, construction, mining, marine, agriculture, energy, industrial manufacturing, and oil & gas operations, and it is fully compatible with Freightliner, Peterbilt, Kenworth, and International truck platforms.

Before installation, thoroughly clean the fuel system, inspect the injector seating bore, replace all seals and O-rings, follow specified torque values, verify ECM calibration, and perform leak and engine performance tests. Recommended service includes regular fuel filter replacement, clean diesel fuel usage, periodic injector return flow testing, and ECM diagnostics to address symptoms such as hard starting, black or white smoke, rough idle, misfire, power loss, or elevated exhaust temperature.
