original 10R-3258 Common Rail Diesel Fuel Injector for C13 Engine Excavator Replacement for OEM 2501309 250-1309 10R3258 10R-3262 10R-3264 original new injector

Engineered for demanding heavy-duty diesel applications, the 10R-3258 fuel injector delivers reliable, high-pressure fuel delivery for the C13 engine platform, including C13 ACERT, C13 Industrial, C13 Generator, and C13 Marine variants. This Electronic Unit Injector (EUI) assembly serves as a direct OEM replacement, cross-referenced with 328-2574, 3282574, and 10R3258, ensuring precise fitment and consistent performance across trucks, construction machinery, mining equipment, generator sets, and marine auxiliary engines.

Manufactured to OEM-quality precision standards, the injector features an optimized fuel spray pattern, high-pressure injection performance, and corrosion-resistant construction for extended service life. Excellent wear resistance and tightly controlled internal tolerances contribute to stable engine power delivery, reduced fuel consumption, and lower exhaust emissions. It effectively addresses common failure symptoms such as difficult starting, black or white smoke, engine misfire, rough idle, excessive fuel consumption, reduced engine power, and check engine light activation, restoring smooth operation to industrial power units and oil & gas equipment.

For optimal performance, thoroughly clean the fuel system before installation, replace injector seals and O-rings, verify the trim/calibration code, follow torque specifications, and complete ECM programming if required. Conduct a fuel leakage inspection and verify injector balance rates after startup. Regular fuel filter replacement, use of ultra-clean diesel, and adherence to OEM maintenance schedules ensure long-term reliability across global export markets including North America, Europe, Middle East, Africa, and Southeast Asia.
