Original MANN‑FILTER Fuel Filter WK 820/15 – For Passenger Cars

The MANN‑FILTER WK 820/15 is a high‑performance fuel filter designed specifically for passenger vehicles that demand reliable protection against contaminants in the fuel system. This component plays a crucial role in maintaining engine efficiency, longevity, and overall vehicle performance.

Key Design Features

• Precision Filtration Media: The filter employs a multi‑layered media structure engineered to capture particles as small as 0.5 µm, ensuring that only clean fuel reaches the engine’s injection system.
• Robust Construction: Constructed from durable, corrosion‑resistant materials, the WK 820/15 withstands harsh operating conditions and extended service intervals without compromising filtration integrity.
• Optimized Flow Path: The internal geometry is specifically engineered to minimize pressure drop while maximizing flow rate, which helps preserve fuel economy and engine responsiveness.
• Easy Installation: Designed for quick replacement, the filter features a standard mounting flange that aligns with most passenger car fuel lines, reducing downtime during maintenance.

Compatibility Overview

The WK 820/15 is engineered to fit a wide range of modern passenger cars. Its dimensions—91 mm outer diameter and 100 mm height—make it suitable for vehicles that require an inline fuel filter with these specifications.

Performance Benefits

• Engine Protection: By filtering out dirt, rust, and other contaminants, the WK 820/15 safeguards fuel injectors, pumps, and valves from premature wear.
• Fuel Efficiency: Clean fuel flow reduces friction within the combustion chamber, contributing to better mileage.
• Reduced Emissions: Consistent fuel delivery promotes complete combustion, lowering harmful exhaust emissions.
• Extended Service Life: The filter’s high‑capacity media allows for longer intervals between replacements without sacrificing performance.

Installation and Maintenance Guidelines

1. Safety First: Ensure the vehicle is parked on a level surface, the engine is cool, and all electrical connections are disconnected to prevent accidental ignition.
2. Drain Fuel System: Follow manufacturer instructions to safely drain residual fuel from the lines before removing the old filter.
3. Remove Old Filter: Loosen the mounting flange bolts, carefully detach the filter housing, and discard the used filter.
4. Install New WK 820/15: Align the new filter’s inlet and outlet ports with the fuel lines. Tighten the mounting bolts to the specified torque (typically 12 Nm, but verify with OEM data).
5. Re‑prime Fuel System: Refill the system with fresh fuel, purge air by cycling the engine, and check for leaks.
6. Verify Operation: Start the engine and observe for any abnormal noises or performance issues. The filter should operate silently under normal conditions.

Quality Assurance

The WK 820/15 is manufactured in accordance with MANN‑FILTER’s stringent quality control standards. Each unit undergoes rigorous testing, including:

• Pressure Drop Test: Ensures the filter maintains acceptable flow resistance under maximum load.
• Contaminant Retention Test: Verifies that the media captures particles down to 0.5 µm.
• Durability Assessment: Simulates extended service intervals to confirm structural integrity.
