The OE: 6460920001 fuel filter is engineered for Mercedes-Benz vehicles equipped with the OM646 diesel engine platform.
It provides high-efficiency filtration for modern common-rail systems by removing fine contaminants and moisture before fuel reaches the high-pressure pump and injectors.
This filter supports smooth engine operation, steady torque delivery, and consistent performance during urban driving and long-distance use.
Its design helps maintain reliable fuel delivery under a wide range of driving environments.
Compatibility
This fuel filter fits Mercedes-Benz models using the OM646 diesel engine, including:
These vehicles depend on clean fuel flow for stable injection behavior.
The filter works as the primary fine filtration stage in the OM646 fuel system.
Its housing structure, inlet ports, and sealing surfaces follow OE specifications for direct installation.
The filter performs reliably in regions with varying diesel quality and supports commercial as well as private use.
Filtration / Material / Mechanical Design
The filter uses a multi-layer synthetic medium designed to capture fine particles without restricting flow.
Its metal housing withstands pressure variations and temperature changes common in diesel operation.
Internal water-separation structures help reduce moisture content in the fuel.
OE-grade seals ensure stable pressure and prevent air entry into the system.
The unit offers dependable performance in dense traffic, warm climates, and long driving cycles.
Flow Stability & Engine Protection
Clean filtration supports precise injector spray patterns and smooth combustion.
The filter contributes to reliable cold-start performance and stable idling.
Consistent fuel purity reduces stress on the high-pressure pump during long-distance or loaded driving.
By eliminating fine contaminants, the filter supports long-term reliability and reduces wear on injection components.

Maintenance Replacement (Official Interval)
Mercedes-Benz diesel platforms recommend replacing the fuel filter every 20,000–30,000 km.
Shorter intervals may be required in areas with inconsistent diesel quality.
Inspection for moisture and debris should occur during regular maintenance.
