Original MANN-FILTER Fuel filter WK 820/16 – For Trucks

Overview of the Original MANN‑FILTER Fuel Filter WK 820/16 – For Trucks

The MANN‑FILTER Fuel Filter WK 820/16 is a high‑performance, OEM‑grade filtration solution designed specifically for heavy‑duty truck engines. Engineered with precision and durability in mind, this filter guarantees optimal fuel cleanliness, protecting the engine’s injection system and extending service intervals.

Key Design Features

• Robust Construction: The filter housing is made from reinforced polypropylene, offering excellent resistance to abrasion, vibration, and temperature extremes typical in truck operations.
• High‑Capacity Media: Equipped with a multi‑layer filtration media that captures particles as small as 5 µm while maintaining low pressure drop for efficient fuel flow.
• Extended Service Life: Designed to last up to 30,000 km (or the manufacturer’s recommended interval) under normal operating conditions, reducing maintenance frequency.
• Seamless Integration: The WK 820/16 fits a wide range of Mercedes‑Benz truck models—including Sprinter, Vito, and Viano—as well as other heavy‑duty vehicles that use the same fuel system architecture.

Compatibility Matrix

The filter’s dimensions (outer diameter 100 mm, height 191 mm) and mounting configuration allow it to be a drop‑in replacement for many OEM filters. Below is a concise compatibility list:

Installation Guide

1. Safety First: Ensure the vehicle is parked on a level surface, engine off, and the fuel system depressurized.
2. Remove Old Filter: Locate the filter housing along the fuel line. Unscrew or unclip the retaining clamp, then carefully detach the old filter, allowing any residual fuel to drain safely.
3. Prepare New Filter: Remove protective seals from the WK 820/16 and inspect for damage. Align the filter’s mounting flange with the housing.
4. Install: Secure the new filter using the original clamp or a compatible locking mechanism. Tighten to manufacturer specifications (typically 1–2 turns of hand‑tightening followed by a torque wrench setting).
5. Check for Leaks: After installation, start the engine and observe the fuel line for any signs of leakage. If detected, re‑tighten or replace seals as necessary.

Performance Benefits

• Engine Protection: By filtering out contaminants, the WK 820/16 safeguards injectors, pumps, and fuel rail components from wear and clogging.
• Fuel Efficiency: A clean fuel stream improves combustion efficiency, potentially reducing fuel consumption by up to 1–2% in heavy‑duty applications.
• Reduced Emissions: Consistent filtration helps maintain optimal engine performance, contributing to lower exhaust emissions and compliance with stringent environmental regulations.
• Reliability Under Stress: The filter’s robust media and housing endure high temperatures, pressure spikes, and harsh road conditions typical of commercial trucking.

Maintenance Tips

• Schedule routine inspections at the manufacturer’s recommended intervals or after prolonged periods of idling in dusty environments.
• Use only OEM‑approved replacement filters to preserve fuel system integrity and avoid compatibility issues.
• Store spare filters in a dry, temperature‑controlled environment to prevent media degradation.
