MANNFILTER Fuel Filter WK 820/14

The WK 820/14 fuel filter from MANNFILTER is a high‑performance component designed to protect the engine of Mercedes-Benz and Infiniti vehicles by removing contaminants from the fuel system. It is engineered for optimal flow, durability, and compatibility with a wide range of models within the A, B, C, E, S, GLA, GLK, Viano, and Vito families.

Key Design Features

• In‑line construction – The filter is mounted directly in the fuel line, ensuring a compact installation that does not interfere with vehicle ergonomics.
• 87 mm outer diameter, 100 mm height – These dimensions provide a large surface area for filtration while fitting standard mounting brackets used across Mercedes-Benz and Infiniti platforms.
• High‑capacity media – The filter medium is engineered to trap particles as small as 1 µm, preventing engine wear and maintaining fuel injector cleanliness.
• Robust housing material – Made from high‑strength polymer, the housing resists corrosion and temperature extremes typical of modern diesel and gasoline engines.
• Easy installation – The filter features a quick‑connect fitting that allows for rapid replacement without special tools or extensive disassembly.

Compatibility Overview

The WK 820/14 is specifically tailored to fit the following vehicle families and engine types:

• Mercedes‑Benz A‑Class (W176), B‑Class (W246), C‑Class (W204, W212), E‑Class (W212, W221, W222), S‑Class (W221, W222), GLA‑Class (X156), GLK‑Class (X204), Viano (W639), and Vito.
• Infiniti Q30/QX30 models equipped with 2.2 L diesel or gasoline engines.
• Engine types – Compatible with both gasoline and diesel fuel systems, including common rail diesel (CRD) and direct injection gasoline engines.

Installation Procedure

1. Safety first: Disconnect the vehicle’s battery to prevent accidental ignition of fuel vapors.
2. Locate the existing filter: The WK 820/14 is typically positioned near the fuel tank, between the tank and the engine.
3. Remove the old filter: Unscrew or detach the quick‑connect fittings. Be prepared for a small amount of fuel to spill; use a catch pan.
4. Install the new WK 820/14: Align the housing with the mounting brackets, secure it, and attach the quick‑connect fittings. Ensure all seals are tight to avoid leaks.
5. Reconnect the battery and test: Start the engine and check for proper fuel pressure and absence of leaks.

Performance Benefits

• Engine protection: By filtering out dirt, rust, and other contaminants, the filter extends the life of fuel injectors and the entire fuel system.
• Improved fuel economy: A clean fuel line reduces engine friction and improves combustion efficiency, leading to marginal gains in mileage.
• Reduced maintenance costs: Replacing a clogged filter before it causes injector damage saves on costly repairs.
• Consistent performance: The filter’s design maintains stable fuel pressure across varying operating temperatures and altitudes.

Quality Assurance & Compliance

The WK 820/14 meets or exceeds all OEM specifications for Mercedes-Benz and Infiniti vehicles. It is manufactured under strict quality control processes, including:

• ISO 9001 certification – Ensures consistent product quality.
• Compliance with DIN 70020 – Guarantees fuel filter performance standards for European markets.
• Rigorous testing: Each batch undergoes pressure drop, flow rate, and contamination resistance tests before shipment.

Maintenance Recommendations

While the WK 820/14 is designed for long service life, regular inspection is advised:

• Check fuel pressure: A drop in pressure may indicate a clogged filter.
• Visual inspection: Look for signs of wear or damage on the housing and fittings.
• Replace at service intervals: Follow manufacturer guidelines, typically every 30,000–50,000 km, depending on driving conditions.

Conclusion

The MANNFILTER WK 820/14 fuel filter is a reliable, high‑quality component that safeguards the performance and longevity of Mercedes-Benz and Infiniti engines. Its precise engineering, broad compatibility, and ease of installation make it an essential part of any vehicle’s maintenance regimen.
