Engineered with precision and built to meet stringent automotive standards, this filter delivers reliable filtration for a wide range of models including Audi, Volkswagen, Skoda, and many others.

Key Design Features

• Compact Dimensions: 81 mm outer diameter and 159 mm height allow seamless integration into tight engine bay spaces.
• Threaded Mounting: Screw‑on construction ensures a secure fit, preventing leaks and maintaining optimal fuel flow.
• Advanced Filter Media: Multi‑layer filtration system captures particulate matter down to sub‑micron levels, preserving fuel injectors and prolonging engine life.
• Durable Housing: Made from high‑grade polymer that resists corrosion, temperature extremes, and chemical exposure.

Performance Characteristics

The WK 842/11 filter is engineered to maintain fuel pressure within the narrow tolerance required by modern fuel injection systems. By removing contaminants such as dirt, rust, and metal shavings, it prevents clogging of injectors and ensures consistent combustion efficiency.

• Pressure Drop: Maintains a low differential pressure across the filter, minimizing engine load.
• Flow Rate: Optimized for high‑volume fuel delivery, supporting both gasoline and diesel engines where applicable.
• Longevity: Designed to last through typical maintenance intervals (usually every 15,000–30,000 km), reducing the need for frequent replacements.

The WK 842/11 filter is compatible with a broad spectrum of passenger cars. Below are representative models that benefit from its precise fit and performance:

• Audi A4 (B5, C5 Avant), Audi A6 (C5 Avant)
• Volkswagen Passat (3B2, 3B3, 3B5, 3B6 variants)
• Skoda Superb (2001‑2008 models)
• Other VAG group vehicles with matching mounting specifications

Installation Guidance

Installing the WK 842/11 filter is straightforward and can be completed without specialized tools:

1. Locate the existing fuel filter. It is typically positioned along the fuel line between the tank and the engine.
2. Disconnect the fuel lines. Use a suitable container to catch any residual fuel.
3. Remove the old filter. Unscrew or unclip according to the vehicle’s design.
