Original MANN‑FILTER Fuel Filter WK 42/1 – For Passenger Cars

The MANN‑FILTER Fuel Filter WK 42/1 is a premium component engineered to protect the engine of passenger vehicles from contaminants that can degrade performance and longevity. Designed with precision, this filter delivers reliable filtration for a wide range of car models, ensuring clean fuel reaches the combustion chamber.

Key Design Features

• High‑Efficiency Filtration Media: The filter employs advanced multi‑layer media that captures particles as small as 0.5 µm, preventing wear on injectors and valves.
• Robust Construction: Constructed from durable polypropylene housing, the filter resists cracking under high pressure and temperature variations typical in modern engines.
• Optimized Flow Path: The internal geometry is engineered to maintain low resistance while maximizing filtration, resulting in minimal impact on fuel pressure.
• Easy Installation: The filter features a standard size that fits most passenger cars without modification. Its clear indicator marks the correct orientation for quick and accurate installation.

Compatibility Overview

The WK 42/1 is engineered to fit an extensive range of vehicles, including but not limited to:

• MERCEDES‑BENZ models such as the W114, W123, and S‑class variants.
• OPEL, RENAULT, CITROËN, FIAT, MAZDA, HONDA, and PEUGEOT.
• Older models like the AUSTIN Ambassador, Bedford Midi, and Renault 4.
• Modern passenger cars from brands such as BMW, CHRYSLER, ISUZU, and SUBARU.

Engineers have validated the filter’s fitment across these platforms, ensuring that the dimensions—50 mm outer diameter, 108 mm height, and 101 mm length—are compatible with standard fuel lines and mounting brackets.

Performance Benefits

• Extended Engine Life: By trapping fine particulates, the filter reduces wear on critical components such as injectors, pistons, and valves.
• Improved Fuel Efficiency: Clean fuel flow maintains optimal combustion, which can translate to better mileage.
• Consistent Power Delivery: The low resistance design ensures that the engine receives steady fuel pressure, preventing power dips during acceleration.
• Reduced Maintenance Costs: With fewer contaminants reaching the engine, routine maintenance intervals can be extended.

Installation Guide

1. Locate the Fuel Filter Housing: Typically positioned along the fuel line between the tank and the engine.
2. Disconnect the Fuel Line: Use a suitable wrench to loosen the fittings, allowing the old filter to be removed without pressure buildup.
3. Remove the Old Filter: Carefully detach the previous filter, noting any orientation marks.
4. Insert the WK 42/1: Align the filter with the correct orientation indicator and secure it in place using the supplied fittings.
5. Reconnect the Fuel Line: Tighten all connections to manufacturer specifications to prevent leaks.
6. Test for Leaks: Start the engine and inspect the installation area for any fuel seepage.

Maintenance Tips

• Replace the filter at intervals recommended by the vehicle manufacturer, typically every 20,000–30,000 km, or sooner if operating in dusty environments.
• Inspect the filter housing for cracks or damage before each replacement to avoid fuel contamination.
• Use only genuine MANN‑FILTER components to maintain warranty and performance standards.
