For Cummins ISX / ISX15 / QSX Series Diesel Engine | Direct Factory Supply | Full Cross-Reference Models in Stock
1. Product Overview
This model 4010225 fuel injector is a brand new aftermarket replacement part independently developed and manufactured by our factory. It is precisely compatible with Cummins ISX CM570, ISX15 CM2250, QSX series diesel engines, and can directly replace the original injector of the same specification.
This injector corresponds to multiple interchangeable cross-reference part numbers for the same ISX/ISX15/QSX engine application. All the part numbers listed on this page are fully compatible and interchangeable, and all corresponding injectors are produced and stocked by our factory, available for direct purchase.
Developed in strict accordance with original factory dimensions and performance standards, it effectively solves engine faults such as poor fuel atomization, power drop, increased fuel consumption and difficult starting. It is widely applicable for maintenance and replacement of heavy-duty trucks, construction machinery, generator sets, marine power and other supporting equipment.
2. Core Product Advantages
① OEM-spec Size, Direct Drop-in Replacement
The product dimensions and interface specifications fully match the original OEM parts. No modification to the fuel line or extra adjustment is required. It can directly replace damaged original injectors, greatly reducing maintenance labor hours and installation costs.
② Precision Calibration, Stable Performance
Each injector undergoes high-precision flow calibration and atomization testing before delivery. The fuel injection pressure, fuel delivery volume and atomization angle are consistent with original factory performance, ensuring full engine combustion, stable power output, and effectively reducing fuel consumption and exhaust emissions.
③ High-quality Materials, Durable Service Life
Core components are made of high-quality alloy materials with wear resistance, high temperature resistance and corrosion resistance. Seals are selected from high-end oil-resistant and durable materials, which can adapt to the complex working environment of heavy-duty high-power diesel engines and extend the service life of the product.
④ 100% Inspection Before Delivery, Controllable Quality
Different from loosely assembled parts on the market, all injectors from our factory are inspected one by one to eliminate unqualified products. The quality consistency of bulk orders is highly reliable, suitable for long-term stable stocking by repair shops and distributors.

6. Installation & Usage Notes
It is recommended that the installation be operated by a professional technician. Before installation, thoroughly clean the engine fuel line to avoid impurities entering the injector and causing damage.
Tighten the fixed parts according to the original factory specified torque during installation to avoid thread or seal structure damage caused by excessive force.
After replacing the injector, it is recommended to match and adjust the engine injection parameters to ensure the best engine operating condition.
Please use qualified diesel that meets the standards. Inferior fuel will greatly shorten the service life of the injector.
We recommend replacing the entire set of fuel injectors to ensure the engine's optimal performance. Due to differences in fuel output and atomization performance between genuine and aftermarket parts, they should not be mixed. Replacing the full set of injectors helps avoid potential operating issues.
