Description
Rebuilt fuel injector set (6 injectors) for Caterpillar 3408 and 3412 diesel engines.
Each injector in the set is professionally rebuilt, ultrasonically cleaned, calibrated, and flow tested to OEM Caterpillar specifications. Every injector is verified before shipping to ensure precise fuel delivery, balanced cylinder performance, and long-term reliability.
This injector set is engineered to:
- Restore precise fuel atomization
- Improve engine power and throttle response
- Reduce excessive smoke and rough engine operation
- Eliminate injector balance and fuel delivery issues
- Support consistent fuel flow across all cylinders
Replacing the full injector set helps maintain balanced engine performance and consistent combustion across all cylinders. For large-displacement Caterpillar engines, matching injectors is critical to achieving maximum efficiency, reliability, and uptime.
This set replaces OEM Caterpillar injector part number 10R0954 and compatible superseded references. Fitment is verified before shipment.
