original Diesel Fuel Injector 239-4909 2394909 for C15 C16 C18 3406E Engine Replacement for OEM 10R-1273 10R-9236 249-0709 Fuel Injectors original new injector

Engineered as a direct OEM alternative, the 239-4909 diesel fuel injector delivers precision-controlled fuel delivery for C15 ACERT engines operating in demanding industrial environments. Cross-referenced with 10R-1273 and 253-0618, this injector assembly is manufactured from high strength alloy steel and calibrated to OEM specifications, ensuring reliable installation into the cylinder head position and seamless integration with existing high-pressure common rail fuel systems.

This injector incorporates advanced atomization technology and high-pressure durability to support consistent combustion across a wide range of operating conditions. Key engineering benefits include improved fuel economy, enhanced combustion efficiency, reduced particulate emissions, increased engine power output, stable idle performance, and faster throttle response. Corrosion resistance and high-temperature endurance extend service life across C15 Industrial, Highway, Construction, Generator, and Marine engine variants. Common diagnostic triggers for injector replacement include difficult engine start, engine vibration, elevated fuel consumption, power reduction, excessive exhaust smoke, abnormal combustion noise, ECU fault codes, and injector balance deviations.

Designed for heavy-duty trucks, mining trucks, excavators, wheel loaders, bulldozers, generator sets, and marine propulsion units, the 239-4909 supports transportation, construction, mining, energy, and marine industry operations. Installation requires disconnecting battery power, cleaning the injector seat, fitting new sealing washers, torque-to-spec installation, fuel system bleeding, and operational verification. Backed by a 12-month warranty for professional B2B procurement.
