Mann Filter WK 720/4 Hummel Fuel Filter

The Mann Filter WK 720/4 Hummel Fuel Filter is a high‑performance component designed to protect the engine of modern gasoline vehicles from contaminants that can impair fuel delivery and reduce efficiency. Engineered by Mann + Hummel, this filter delivers superior filtration while maintaining low resistance to airflow, ensuring optimal combustion performance.

Key Features

• Advanced Filtration Technology: Utilizes a multi‑layered media system that captures particles as small as 0.5 µm, preventing wear on fuel injectors and maintaining engine longevity.
• Low Pressure Drop: Engineered to provide minimal resistance to the fuel flow, preserving throttle response and power output.
• Durable Construction: Made from high‑quality polypropylene housing with reinforced edges for long service life even under harsh operating conditions.
• Easy Installation: Designed for quick replacement without special tools; the filter’s shape matches standard mounting points on most vehicles.
• Compatibility: Suitable for a wide range of gasoline engines, including those found in Audi, Seat, Lamborghini, and other VAG group cars.

Vehicle Compatibility

The WK 720/4 is specifically engineered to fit the following vehicle models:

• Audi A4 (8ED, B7) – both sedan and Avant variants
• Audi A6 (C6, 4F5) – including Limousine and Avant versions
• Seat Exeo – 1.8‑5.2 TFSI engines
• Lamborghini models that use the same fuel system architecture as VAG group cars
• Other compatible vehicles with a 4‑port fuel filter housing and similar inlet/outlet dimensions.

Installation Guide

1. Safety First: Ensure the engine is cool, disconnect the battery, and relieve any pressure in the fuel system by opening the fuel cap or using a vacuum pump.
2. Locate the Filter: The WK 720/4 sits between the fuel tank and the engine’s fuel rail. It is typically mounted on a bracket with two mounting screws.
3. Remove Old Filter: Unscrew the mounting bolts, carefully detach the filter housing, and allow any residual fuel to drain into a suitable container.
4. Install New Filter: Place the new WK 720/4 onto the bracket, align the inlet/outlet ports with the fuel lines, and secure it with the original screws. Ensure the filter is seated properly to avoid leaks.
5. Reconnect Battery & Test: Reconnect the battery, start the engine, and check for any signs of leakage or abnormal noise. The engine should run smoothly if installation was correct.

Maintenance Tips

• Replace the filter every 20 000–30 000 km or as recommended by the vehicle manufacturer to maintain optimal fuel quality.
• Avoid using aftermarket filters that do not meet Mann + Hummel specifications, as they may compromise engine performance.
• Inspect the filter housing for cracks or damage before each replacement; replace if necessary.
