Original MANN-FILTER Fuel filter WK 822/3 – For Passenger Cars

MANN‑FILTER Fuel Filter WK 822/3 – For Passenger Cars

The WK 822/3 fuel filter from MANN‑FILTER is engineered specifically for passenger cars that demand reliable protection of the fuel system. This high‑performance filter delivers exceptional filtration efficiency, ensuring that only clean, contaminant‑free fuel reaches the engine’s injectors and combustion chambers.

Key Design Features

• Advanced Filtration Media: The filter incorporates a multi‑layered media system that captures particles as small as 0.5 µm, preventing wear on fuel injectors and maintaining optimal combustion.
• Robust Construction: Constructed from durable polypropylene housing, the filter resists corrosion and withstands high pressure environments typical of modern gasoline engines.
• Compact Size: With a streamlined profile, the WK 822/3 fits easily into standard passenger car fuel lines without requiring modifications to the vehicle’s architecture.
• Low Flow Resistance: Designed to maintain engine performance, the filter offers minimal pressure drop across the unit, ensuring that fuel flow remains consistent even under demanding operating conditions.

Compatibility and Vehicle Coverage

The WK 822/3 is tailored for a wide range of passenger cars. It is commonly found in models such as:

• MERCEDES‑BENZ S‑Class, E‑Class, and ML‑Series vehicles.
• Other premium and mainstream passenger car brands that utilize similar fuel system specifications.

Because the filter adheres to strict MANN‑FILTER quality standards, it can be confidently installed in any vehicle that requires a fuel line filter with a 105 mm diameter, ensuring seamless integration into existing systems.

Performance Benefits

• Engine Longevity: By trapping contaminants before they reach the fuel injectors, the WK 822/3 reduces injector wear and prolongs engine life.
• Fuel Efficiency: Clean fuel flow promotes optimal combustion efficiency, which can translate into better mileage and reduced emissions.
• Reliability: The filter’s robust construction and low pressure drop guarantee consistent performance even under high‑temperature or high‑pressure conditions.

Installation Guidelines

1. Safety First: Ensure the vehicle is parked on a level surface, engine off, and the fuel system depressurized before beginning work.
2. Locate the Existing Filter: Identify the current fuel filter in the line between the fuel tank and the engine. The WK 822/3 will replace this unit.
3. Disconnect Fuel Lines: Carefully disconnect the upstream and downstream fittings, taking care to avoid spills or leaks.
4. Install the WK 822/3: Attach the new filter using the supplied fittings. Tighten connections securely but avoid overtightening to prevent damage.
5. Re‑pressurize and Test: Once installed, re‑pressurize the fuel system according to vehicle specifications and check for leaks before starting the engine.

Maintenance Recommendations

The WK 822/3 is designed as a single‑use component. For optimal performance, replace the filter at regular intervals specified by the vehicle manufacturer or after every 10,000–15,000 miles of operation. Regular replacement prevents clogging and ensures that fuel delivery remains clean and efficient.

Quality Assurance

MANN‑FILTER is a globally recognized brand known for its rigorous testing protocols. Each WK 822/3 unit undergoes:

• Pressure drop testing to confirm low resistance under load.
• Particle retention analysis to verify filtration efficiency.
• Durability assessments against temperature and chemical exposure.

These tests guarantee that every filter meets or exceeds industry standards, providing peace of mind for vehicle owners who demand the best for their engines.

Conclusion

The MANN‑FILTER Fuel Filter WK 822/3 stands out as a reliable, high‑performance solution for passenger cars that require pristine fuel delivery. Its advanced filtration media, durable construction, and low flow resistance combine to protect engines, enhance efficiency, and extend vehicle lifespan. Whether you’re maintaining a fleet of premium vehicles or caring for a single passenger car, the WK 822/3 delivers uncompromised quality and performance.
