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

The 1111402AED09 fuel filter assembly fits GWM Wingle 6 diesel models using the GW4D20, GW4D20D, and GW4D20M engine families.
It captures fine particles and moisture before fuel reaches the high-pressure pump, supporting smooth performance and stable torque.
This filter cross-references with 1111402AED10 and 1111402XED09, covering the complete Wingle 6 diesel fine-filtration group.

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.

Interchangeable OE Numbers (Cross-Reference)

Technicians should inspect for moisture or debris during scheduled service.

Sourcing & Ordering FAQ

❓ Is this product suitable for my market?

Product suitability depends on operating conditions, usage intensity, and local expectations.

We evaluate product recommendations based on real application scenarios,

not just vehicle compatibility.

❓ Do you supply OEM or aftermarket versions?

Depending on the product, we can support OEM-standard or verified aftermarket options.

The recommendation is based on quality stability, cost structure, and market positioning — not labels.

❓ Can this product be combined with other parts in one shipment?

Yes.

Consolidated sourcing across categories is one of our core strengths,

helping buyers reduce freight cost and inventory pressure.

❓ How is quality controlled before shipment?

All products are inspected before shipment.

We work with factories that maintain stable production processes rather than short-term output.

❓ Can I start with a trial order?

Yes.

Trial orders are encouraged for new cooperation,

especially for engine and cooling system service parts where consistency matters.
