Mann Filter Diesel Fuel Filter for Mercedes‑Benz Sprinter — WK 842/23 x, Water‑Sensor Connection, High‑Efficiency

MANN-FILTER WK 842/23 x is a high-efficiency diesel fuel filter with integrated water separation and sensor connection designed for select Mercedes‑Benz Sprinter models.

This replacement fuel filter protects your engine’s injection components by trapping dirt, rust and water before they reach sensitive parts. Built with premium media and materials, the WK 842/23 x is engineered to deliver consistent fuel flow, excellent separation performance and durability for extended service intervals. It fits Sprinter applications that require a water-sensor connection and matches multiple OE part numbers for straightforward cross-referencing.

How does this filter protect the fuel system?

The WK 842/23 x uses high-efficiency filter media that captures particles and impurities while a dedicated water separation stage removes free water from diesel. By keeping contaminants out of the injection system, it helps maintain performance and reduces wear on pumps and injectors. The integrated sensor interface alerts you when water accumulation needs attention.

• High-efficiency filter media traps dust, rust and dirt
• Designed to separate and retain almost 100% of free water under test conditions
• Sensor connection compatible with vehicle water-detection systems
• Reduces risk of injector damage by precluding contaminants

What fitment and compatibility should I expect?

This MANN-FILTER part is specified for select Mercedes‑Benz Sprinter models that use a water-sensor fuel filter. It corresponds to several OE numbers used by Mercedes, making it suitable for cross-reference during replacement. Always verify the OE number and the water-sensor plug type on your vehicle before purchasing.

• Compatible with vehicles requiring water-sensor connection
• Cross-references multiple OE numbers listed by Mercedes‑Benz
• Check vehicle's existing filter OE number for exact match

How does the WK 842/23 x affect fuel flow and engine performance?

The filter is engineered to provide optimal fuel flow with minimal pressure drop so your injection system receives consistent supply under load. Efficient filtration and near-complete water separation maintain clean fuel reaching the injectors, which supports steady combustion and throttle response. Using the correct filter minimizes the chance of clogs and keeps service intervals predictable.

• Optimized internal design for minimal pressure loss
• Reliable flow rates maintain injector supply even under stress
• Cleaner fuel helps stabilize combustion and responsiveness
