Mann-Filter WK 820/23 is a diesel fuel filter with water separator from Germany-based filtration expert Mann+Hummel. This OE-style aftermarket replacement delivers clean fuel to protect the fuel pump and injectors in select Mercedes-Benz Sprinter vans. The filter uses advanced filtration and water separation to remove contaminants and water from diesel, helping prevent corrosion and injector scoring. Check the number on the original filter before buying, as mixed installation occurred from the factory.

Replacing a clogged or water-contaminated filter reduces fuel flow restrictions, improves starting, and maintains steady engine performance. Common symptoms include reduced power, rough idle, or increased fuel consumption. The WK 820/23 is designed for reliable, engineered filtration and aligns with OEM specifications for durable, long-term diesel fuel system protection. An aftermarket replacement that emphasizes quality and reliability from Mann-Filter.
