Original MANN‑FILTER Fuel Filter WK 822/1 – For Passenger Cars

The MANN‑FILTER Fuel Filter WK 822/1 is a premium, OEM‑grade component designed specifically for passenger cars that require the highest level of fuel cleanliness and engine protection. Engineered by MANN‑FILTER, one of the world’s leading filter manufacturers, this unit delivers exceptional filtration performance while maintaining optimal fuel flow.

Key Design Features

• High‑Efficiency Filtration Media: The filter uses a multi‑layered media system that captures particles as small as 0.5 µm, ensuring that only the cleanest fuel reaches the engine.
• Low Pressure Drop: Despite its fine filtration capability, the WK 822/1 maintains a minimal pressure drop, preserving fuel pressure and preventing any loss of power or efficiency.
• Durable Construction: The housing is made from high‑strength polypropylene, resistant to corrosion and chemical attack, guaranteeing long service life even under harsh operating conditions.
• Standardized Size: With an outer diameter of 85 mm and a height of 105 mm, the filter fits seamlessly into most passenger car fuel systems that require the WK 822/1 specification.
• Easy Installation: The design incorporates a quick‑release valve and a secure mounting flange, allowing for rapid replacement without special tools.

Compatibility Overview

The WK 822/1 is engineered to match the original equipment specifications of numerous passenger car models. It is fully compatible with:

• MERCEDES‑BENZ C‑CLASS (W203, S203)
• CLK (C209) and G‑CLASS variants
• M‑CLASS (W163) models
• Various other passenger car platforms that specify the WK 822/1 size and performance criteria.

Because of its OEM certification, the filter guarantees the same level of protection as the original factory unit, preserving engine integrity and maintaining manufacturer warranty terms.

Performance Benefits

• Engine Protection: By trapping contaminants such as dirt, rust particles, and water droplets, the filter prevents abrasive wear on fuel injectors, pumps, and other critical components.
• Fuel Efficiency: Clean fuel flow reduces friction within the fuel system, contributing to better combustion efficiency and potentially lower fuel consumption.
• Reduced Maintenance Intervals: The high‑capacity media allows for longer service intervals compared to standard filters, reducing overall maintenance costs.
• Consistent Performance: The filter’s design ensures stable pressure across a wide range of operating temperatures and altitudes.

Installation & Maintenance Guidelines

While the WK 822/1 is designed for straightforward replacement, following these steps guarantees optimal performance:

1. Safety First: Disconnect the battery and relieve fuel system pressure before beginning.
2. Remove Old Filter: Unscrew the mounting flange and carefully detach the filter housing. Dispose of the used filter according to local regulations.
3. Inspect Fuel Lines: Check for leaks or damage; replace any compromised components.
4. Install New Filter: Align the new WK 822/1 with the mounting flange, ensuring a snug fit. Tighten securely but avoid overtightening to prevent housing cracks.
5. Re‑pressurize System: Reconnect the battery and restore fuel pressure. Verify that there are no leaks and that the filter operates within normal parameters.

Quality Assurance & Certification

The WK 822/1 meets stringent European Union EN 14214 standards for automotive fuel filters, guaranteeing:

• Particle Retention: Minimum 99.9 % removal of particles ≥0.5 µm.
• Pressure Drop: Not exceeding 1.2 kPa at a flow rate of 10 L/min.
• Chemical Resistance: Compatibility with gasoline, diesel, and ethanol blends up to 10 % E10.
