Engineered specifically for the C13 platform, the 239-4908 fuel injector delivers OEM-equivalent fuel metering precision across the entire C13 engine family, including the C13 ACERT, C13 Industrial, C13 Generator Set, C13 Marine Power Unit, and C13 Truck Engine variants. Manufactured from hardened alloy steel with an anti-corrosion surface treatment, this common rail injector assembly is calibrated to factory flow rates and validated through 100% flow testing to ensure consistent injection performance, low leakage, and stable thermal behavior under the high-pressure demands of modern heavy-duty diesel operation. It is fully interchangeable with reference numbers 10R-1273, 253-0616, 328-2574, 387-9433, and 20R-8064, allowing direct replacement without modification.

This injector is purpose-built to match the fuel system architecture of C13 engines deployed in mining trucks, haul trucks, excavators, wheel loaders, bulldozers, motor graders, diesel generator sets, backup power systems, marine auxiliary engines, marine propulsion systems, oilfield pumping units, drilling rigs, and road construction equipment. The precision nozzle geometry promotes superior fuel atomization and more complete combustion, which translates into improved engine power output, reduced fuel consumption, lower particulate emissions, and noticeably quieter operation across high-load industrial and off-highway duty cycles.

Backed by a 12-month warranty and supplied in export-standard packaging with a minimum order quantity of one piece, the injector also supports OEM service and private label options for distributors and fleet operators. Routine maintenance recommendations include the use of clean diesel fuel, scheduled filter replacement, regular fuel pressure monitoring, periodic leak inspection, and injector balance testing following OEM service intervals. Proper installation requires battery disconnection, injector bore cleaning, replacement of seals and washers, torque application to OEM specifications, fuel system priming, and ECM diagnostics to confirm optimal C13 engine performance.
