Original MANN-FILTER Fuel filter WK 728 – For Passenger Cars

MANN-FILTER Fuel Filter WK 728

The MANN‑FILTER Fuel Filter WK 728 is a high‑performance, OEM‑grade filtration solution designed specifically for passenger cars that require precise fuel purity and reliable engine protection. Engineered with advanced materials and rigorous testing standards, this filter delivers exceptional contaminant removal while maintaining optimal fuel flow.

Key Design Features

• Precision Filtration Media: Utilizes a multi‑layered polyester fiber core that captures particles as small as 0.5 µm, ensuring the engine receives clean fuel free from dirt, rust, and debris.
• Optimized Flow Resistance: The filter’s geometry balances low pressure drop with high filtration efficiency, preserving fuel pressure for efficient combustion.
• Durable Housing: Constructed from reinforced polypropylene, the housing resists corrosion and withstands the harsh environment of the fuel line.
• Standardized Dimensions: Outer diameter of 76 mm and height of 162 mm allow seamless integration into a wide range of vehicle models without modification.
• Quick‑Fit Installation: Designed for in‑line replacement, the filter can be installed or serviced with minimal tools, reducing downtime during maintenance.

Vehicle Compatibility

The WK 728 is engineered to fit a broad spectrum of passenger vehicles, particularly those from Mitsubishi and other manufacturers that share similar fuel system specifications. Common applications include:

• Mitsubishi Grandis (model codes: 1770A024)
• Lancer VIII Limousine
• Outlander II SUV
• Space Wagon variants
• Other passenger cars with a 76 mm outer diameter fuel line and 162 mm filter height requirement.

Because the filter meets OEM specifications, it is fully compatible with the original fuel system design, ensuring that performance and reliability are maintained without compromising engine integrity.

Performance Benefits

• Engine Protection: By trapping contaminants before they reach the fuel injectors or pump, the filter prevents wear, clogging, and potential failure of critical components.
• Fuel Efficiency: Clean fuel flow reduces friction within the injection system, contributing to smoother engine operation and potentially improved mileage.
• Longevity: The robust construction and high‑grade media extend the service life of the filter, allowing for longer intervals between replacements compared to lower‑quality alternatives.
• Consistent Performance: Maintains stable pressure drop across a wide range of operating temperatures, ensuring reliable engine performance in both hot and cold climates.

Installation & Maintenance Guidelines

Proper installation is critical to achieving the full benefits of the WK 728. Follow these steps for optimal results:

1. Disconnect the vehicle’s battery to prevent accidental ignition.
2. Relieve fuel system pressure using a dedicated pump or by draining the line.
3. Remove the existing filter carefully, noting the orientation of the flow direction indicator.
4. Align the new WK 728 with the correct flow direction and secure it in place using the supplied mounting hardware.
5. Reconnect the battery and perform a fuel system pressure test to ensure no leaks.
6. Start the engine and observe for any abnormal noises or performance issues; if none, the filter is installed correctly.

For routine maintenance, replace the filter at intervals recommended by the vehicle manufacturer or when a noticeable drop in fuel pressure occurs. The WK 728’s design allows for quick removal and replacement without specialized tools.

Quality Assurance & Compliance

• The filter is manufactured under strict quality control protocols that align with ISO/TS 16949 standards, ensuring consistency across every unit.
• It complies with automotive industry specifications for fuel filtration, including ASTM D-7466 and SAE J1349.
• Each batch undergoes pressure drop testing, particle retention analysis, and durability assessments to guarantee performance under real‑world conditions.

Environmental Impact

The WK 728’s high filtration efficiency reduces the amount of particulate matter released into the environment by preventing contaminants from entering the combustion chamber. Additionally, its durable construction means fewer replacements are needed over the vehicle’s lifespan, contributing to lower resource consumption and waste generation.

Conclusion

The MANN‑FILTER Fuel Filter WK 728 represents a blend of advanced engineering, reliable performance, and ease of maintenance. Its precise filtration media, robust construction, and compatibility with a wide range of passenger vehicles make it an essential component for protecting engine health and ensuring optimal fuel system operation.
