Original MANN-FILTER Fuel Filter WK 939/3 – For Passenger Cars

MANN‑FILTER Fuel Filter WK 939/3 – Essential for Passenger Cars

The MANN‑FILTER Fuel Filter WK 939/3 is a high‑performance component designed to protect the fuel system of passenger vehicles. It is engineered to meet stringent European standards and is compatible with a wide range of models, particularly those from the Renault family such as the Clio II, Clio III, Modus, and Grandtour.

Key Features

• Advanced Filtration Technology: Utilises a multi‑layer filter media that captures particles down to 0.5 µm, ensuring the fuel remains clean and free from contaminants that could damage injectors or fuel pumps.
• Durable Construction: Made with high‑quality polypropylene housing, the filter resists corrosion and maintains structural integrity under varying temperature and pressure conditions.
• Low Pressure Drop: Designed to minimise resistance in the fuel line, which helps maintain optimal engine performance and fuel economy.
• Easy Installation: Features a standard threaded connection that fits most passenger car fuel lines without requiring additional adapters or modifications.
• Long Service Life: Engineered to last through the typical mileage range of modern vehicles, reducing the need for frequent replacements.

Compatibility and Applications

The filter is specifically tailored for use in passenger cars. It is a direct fit for numerous Renault models, including:

• Renault Clio II (BB0/1/2_, CB0/1/2_)
• Renault Clio III (BR0/1, CR0/1)
• Renault Modus and Grandtour

Its universal design also allows it to be used in other vehicles that require a fuel filter with the same specifications. The product is available under various regional names such as “Kraftstofffilter” (German), “Filtro de combustible” (Spanish), “Filtre à carburant” (French), and “Brændstof-filter” (Danish). Regardless of language, the underlying component remains identical.

Installation Guide

1. Locate the existing fuel filter on your vehicle’s fuel line. It is typically positioned near the fuel tank or along the main fuel feed.
2. Disconnect the fuel line by loosening the fittings and allowing any residual pressure to release safely.
3. Remove the old filter, taking care not to spill any remaining fuel.
4. Attach the new MANN‑FILTER WK 939/3 by aligning the threaded ends with the fuel line fittings. Tighten securely but avoid over‑tightening to prevent damage.
5. Reconnect the fuel lines and check for leaks. Once confirmed, start the engine to ensure proper operation.

Maintenance Tips

• Inspect the filter regularly if your vehicle operates in dusty or high‑contamination environments.
• Replace the filter at recommended intervals based on mileage and driving conditions; this prolongs engine life and maintains fuel efficiency.
• Avoid using incompatible filters, as they may not provide adequate protection and could lead to premature wear of fuel system components.
