FAQ

Q: Is this injector a direct fit for my CAT C4.4 engine, or will it require modification?
A: This is a direct, bolt-on replacement part. It is engineered to the exact physical and performance specifications of the original OEM injector (320-0677). No modifications are required for proper installation.

Q: What precautions should be taken during installation to ensure optimal performance?
A: For best results, always clean the injector seat in the cylinder head thoroughly before installation. Use new sealing washers or O-rings. It is also highly recommended to have the injector coding programmed into the Engine Control Module (ECM) by a qualified technician to ensure perfect calibration and engine performance.

Q: Do you provide technical support or compatibility verification for specific machine serial numbers?
A: Yes. While this injector is designed for the C4.4 and C6.6 engine platforms, we recommend providing your equipment model and serial number prior to purchase. Our technical team can assist in verifying the exact part number compatibility for your specific application to ensure a correct fit.
