OE: 1111402AED09 Fuel Filter Assembly for GWM Wingle 6 Diesel | Great Wall

The OE: 1111402AED09 fuel filter assembly is the main fine filtration unit for GWM Wingle 6 diesel models, supporting the needs of modern common-rail engines.
It captures fine particles and moisture before fuel enters the high-pressure pump and injectors.
This filtration stage helps maintain smooth combustion, stable torque delivery, and consistent performance during daily driving and commercial use.

Compatibility

This fuel filter assembly fits Wingle 6 diesel platforms, powered by:

• GW4D20 diesel engine

• GW4D20D upgraded version

• GW4D20M enhanced common-rail variant

Wingle 6 models are widely used in global markets where fuel quality can vary.
The filter integrates with the truck’s two-stage diesel filtration system, working after the pre-filter.
Its housing, sealing points, and connectors match OE specifications for direct installation.
The assembly supports stable operation in mixed urban, rural, and highway environments.

Filtration / Material / Mechanical Design

The unit features a multi-layer synthetic filtration medium designed to capture fine contaminants without limiting flow.
Its durable aluminum housing handles pressure changes during towing, load transitions, and temperature shifts.
Internal water-separation channels help reduce moisture within the fuel supply.
OE-grade sealing interfaces ensure accurate fitment and stable pressure throughout the system.
The filter performs reliably in dusty regions, warm climates, and long working hours typical of Wingle 6 usage.

Flow Stability & Engine Protection

Clean fuel supports accurate injector spray patterns and predictable torque.
The assembly helps improve cold-start reliability and maintain smooth idling.
Stable filtration reduces stress on the high-pressure pump during heavy-duty tasks.
By keeping contaminants away from sensitive components, the filter supports long-term system reliability and steady engine performance.
