Original MANN-FILTER Fuel filter WK 516/2 – For Passenger Cars

MANN‑FILTER Fuel Filter WK 516/2

The MANN‑FILTER Fuel Filter WK 516/2 is a high‑performance in‑line fuel filter designed specifically for passenger cars, with a strong focus on BMW and AlpinA models. It delivers reliable protection against contaminants that can damage the engine’s fuel system, ensuring optimal combustion efficiency and prolonging engine life.

Key Design Features

• In‑line construction: The filter is built as a single unit that fits directly into the existing fuel line without requiring additional fittings or adapters. This simplifies installation and reduces the risk of leaks.
• 55 mm outer diameter, 330 mm height: These dimensions match the standard fuel lines used in many BMW 5‑Series (E39/E52) and AlpinA Roadster models, providing a perfect fit for vehicles such as the Z8, M5, and V8 variants.
• High filtration efficiency: The filter media captures particles down to 0.3 µm with a retention rate of over 99.9%, protecting fuel injectors, pumps, and other critical components from wear.
• Durable housing: Made from high‑strength polymer, the housing resists corrosion and temperature extremes typical in automotive fuel systems.
• OEM compatibility: The WK 516/2 is engineered to meet or exceed original equipment manufacturer (OEM) specifications for BMW and AlpinA vehicles, ensuring seamless integration with existing engine management systems.

Performance Benefits

The MANN‑FILTER Fuel Filter WK 516/2 offers several tangible advantages for vehicle owners:

• Engine protection: By trapping dirt, rust, and other contaminants, the filter prevents abrasive particles from reaching fuel injectors and pumps, reducing wear and extending component life.
• Fuel economy: A clean fuel system allows the engine to operate at peak efficiency, which can translate into better mileage and reduced emissions.
• Reliability: Consistent filtration performance means fewer unexpected failures or maintenance issues related to contaminated fuel.
• Ease of replacement: The filter’s standard size and in‑line design make it straightforward for mechanics or DIY enthusiasts to replace during routine service intervals.

Installation Overview

Replacing the WK 516/2 is a simple procedure that can be completed with basic tools:

1. Locate the existing fuel filter in the vehicle’s fuel line (typically near the fuel tank or along the main feed to the engine).
2. Disconnect the fuel lines, ensuring you have a catch container for any residual fuel.
3. Remove the old filter and discard it properly.
4. Insert the new WK 516/2 into the same position, aligning the threaded ends with the fuel line fittings.
5. Tighten all connections securely, then restore fuel pressure by re‑pressurizing the system or allowing the engine to start.
6. Check for leaks and verify that the vehicle’s engine control unit (ECU) registers normal operation.

Compatibility Summary

The WK 516/2 is specifically engineered for:

• BMW 5‑Series models (E39, E52) including the Z8 Roadster and M5 variants.
• AlpinA Roadster and other high‑performance BMW derivatives that share the same fuel line architecture.
• Vehicles equipped with a 55 mm outer diameter fuel line and requiring an in‑line filter of 330 mm height.

Quality Assurance

MANN‑FILTER is renowned for its rigorous quality control processes. Each WK 516/2 unit undergoes:

• Pressure testing to ensure the housing can withstand operating pressures up to 10 bar.
• Filtration efficiency tests that confirm particle retention rates above 99.9% for particles ≥0.3 µm.
• Material durability assessments, including corrosion resistance and temperature tolerance up to 120 °C.

Maintenance Tips

• Replace the filter at recommended intervals (typically every 20,000–30,000 miles or as specified by the vehicle manufacturer) to maintain optimal performance.
• Avoid using aftermarket filters that do not meet OEM specifications, as they may compromise fuel system integrity.
• Inspect fuel lines for signs of wear or damage before installing a new filter; replace any compromised components immediately.

Conclusion

The MANN‑FILTER Fuel Filter WK 516/2 is an essential component for owners of BMW and AlpinA passenger cars who demand reliable engine protection, superior fuel efficiency, and peace of mind. Its precise engineering, proven filtration performance, and straightforward installation make it the preferred choice for both professional mechanics and knowledgeable DIY enthusiasts.
