original Fuel Injector 188-8739 172-5780 217-2570 235-2888 235-9649 10r-7224 For C7 C9 330C E330 E336d 1 Year Warranty  original new injector

The 188-8739 fuel injector is engineered specifically for the C7 and C7 ACERT engine platforms, delivering OEM-equivalent fitment and performance for demanding industrial and mobile applications. Utilizing Electronic Unit Injection technology, this injector provides precise high-pressure fuel atomization, ensuring accurate fuel metering across all engine operating conditions. The assembly is constructed from high-strength hardened steel with corrosion-resistant materials, featuring precision-machined internal components that meet original dimensional tolerances for direct replacement without modification.

This injector is fully compatible with the C7 diesel engine family deployed across excavators, wheel loaders, bulldozers, motor graders, mining trucks, generator sets, commercial vessels, heavy-duty trucks, and agricultural machinery. It serves as a direct replacement for OE numbers 10R0955, 236-0962, 387-9433, and 10R4761, supporting engine configurations in construction, mining, marine, agricultural, and power generation sectors. The injector undergoes multi-point quality inspection to verify spray pattern, flow rate, and electrical performance before shipment.

The 188-8739 injector improves combustion efficiency, reduces fuel consumption, and lowers exhaust emissions while increasing engine power output and enhancing overall reliability. Its heavy-duty industrial durability design ensures long service life even in harsh operating environments. For optimal performance and longevity, operators should use high-quality diesel fuel, replace fuel filters regularly, prevent water contamination, monitor fuel pressure, inspect fuel lines periodically, and follow recommended maintenance schedules.
