Engineered as a direct OEM-grade replacement, the 212-3464 Fuel Injector is a precision-built Electronic Unit Injector (EUI) designed for C10 and C12 diesel engine platforms. Fully interchangeable with cross reference numbers 10R-0957 and 20R-2057, this injector delivers accurate fuel metering, stable injection pressure, and superior atomization performance—critical requirements for high-load industrial and heavy-duty applications. Every unit is manufactured to strict dimensional tolerances and undergoes factory performance testing to ensure long-term reliability in demanding operating environments.

Built with corrosion-resistant materials and high-durability internal components, the 212-3464 injector supports improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, and enhanced cold-start behavior. It is widely deployed across heavy duty trucks, excavators, wheel loaders, mining machinery, generator sets, marine propulsion systems, oilfield equipment, and agricultural machinery. With a global service footprint covering North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia, it is trusted by fleet operators, OEM workshops, and industrial power distributors.

Recommended installation practices include cleaning the injector bore, replacing sealing components, verifying harness condition, confirming ECM compatibility, and applying OEM torque specifications. Routine maintenance—clean diesel fuel, regular filter replacement, and periodic diagnostics—maximizes service life and prevents symptoms such as excessive smoke, reduced horsepower, and stored ECM fault codes.
