original 20R-5353 Diesel Fuel Injector Nozzle Assembly for C15 C18 C27 C32 Excavator Engine Injection Valve Replacement for OEM 295-9085 10R8988 Spare Parts original new injector

Engineered as a direct-fit replacement for the C15 heavy duty diesel platform, the 20R-5353 fuel injector delivers factory-calibrated performance for demanding industrial, marine, and on-highway applications. This injector assembly is fully cross-referenced with 10R-7224 (also listed as 20R5353 and 10R7224), ensuring seamless interchangeability across C15, C15 ACERT, and 3406E engine configurations. Built to OEM remanufactured standards, each unit is designed to restore original fuel delivery accuracy and combustion efficiency in Electronic Unit Injector (EUI) fuel systems.

Precision nozzle engineering, hardened wear-resistant components, and corrosion-resistant materials support extended service life under high-pressure injection cycles. Factory calibration provides precise fuel delivery, improved combustion efficiency, enhanced horsepower output, reduced fuel consumption, lower particulate emissions, stable idle operation, and faster throttle response. The 20R-5353 addresses common failure symptoms such as hard starting, power loss, rough idle, black or white exhaust smoke, misfires, and elevated emissions, making it a reliable solution for fleet maintenance programs.

Applications span highway trucks, mining trucks, excavators, wheel loaders, generators, marine propulsion, and oilfield equipment across global markets. For optimal service life, use high-quality diesel fuel, replace all seals and O-rings during installation, follow torque specifications, and verify fuel pressure and calibration after fitment.
