original Fuel Injector 212-3464 for NT855 C10 C12 3176 Engine Assembly Components Loader Excavator Truck Diesel Parts  original new injector

Engineered specifically for the C12 engine family, the 212-3464 fuel injector delivers precise fuel metering and consistent atomization across the full operating range of this 11.9-liter inline six-cylinder platform. With turbocharged aspiration, water-cooled architecture, and electronic unit injection governing output from 355HP to 505HP, the C12 demands injector components calibrated to its original flow parameters. This 212-3464 unit is manufactured to match those specifications, ensuring correct injection timing, balanced cylinder contribution, and stable rail pressure under heavy-duty load conditions encountered in on-highway trucks, marine propulsion packages, and stationary generator sets.

The injector integrates precision-lapped nozzle assemblies, hardened internal wear components, and a high-response solenoid design capable of withstanding sustained injection pressures within the EUI system. Each unit is factory flow-tested and calibrated to OEM reference standards, with corrosion-resistant materials selected for long service life in diesel fuel environments. Built as a direct-fit replacement, the 212-3464 installs into the cylinder head using existing fuel lines and electrical connections, with proper seating dependent on clean injector bores, fresh sealing O-rings, and adherence to torque specifications. ECM calibration should be verified following installation, and a post-installation leak test along with return-flow verification is recommended to confirm injector performance.

Compatible with C12 ACERT variants and widely deployed in Freightliner, Peterbilt, Kenworth, and International truck configurations, this 212-3464 injector supports transportation, construction, mining, marine, agricultural, energy, and oil and gas operations worldwide. Typical symptoms of a failing C12 injector including hard starting, rough idle, power loss, excessive black or white smoke, elevated exhaust temperature, increased fuel consumption, and engine misfire can often be traced to compromised injection components. Replacing with this OEM-equivalent 212-3464 unit restores combustion efficiency, reduces exhaust emissions, and returns the engine to specified performance benchmarks. A 12-month warranty applies, and global export supply is available for distributor and fleet maintenance programs.
