Original MANN-FILTER Oil filter W 820 – For Passenger Cars

MANN‑FILTER Oil Filter W 820

The MANN‑FILTER Oil Filter W 820 is a high‑performance filtration solution engineered specifically for passenger cars. Designed with precision and built to meet the demanding requirements of modern engines, this filter delivers exceptional protection against contaminants while maintaining optimal oil flow.

Key Design Features

The filter incorporates a dual‑stage filtration system that captures particles as small as 5 µm. The first stage uses a pre‑filter to trap larger debris, while the second stage employs a fine media layer for microscopic contaminants. This two‑tier approach ensures prolonged oil life and reduces engine wear.

A single anti‑return valve is integrated into the housing, preventing backflow of contaminated oil during shutdown or low pressure conditions. The valve also protects the filter from reverse flow that could compromise its integrity.

The filter’s body is constructed from a durable polymer blend, offering resistance to high temperatures and chemical degradation. Its 114 mm outer diameter and M20×1.5 thread size provide a secure fit on a wide range of engine housings.

Compatibility and Applications

The W 820 is engineered for use in a variety of passenger car engines, including models from Ford, Fiat, Citroën, and other European manufacturers. It is suitable for both gasoline and diesel engines that require a 114 mm filter with an M20×1.5 thread.

Common applications include:

• Citroën C25 – van and chassis models
• Ford Fiesta, Focus, Mondeo
• Fiat 500, Panda, Tipo
• Other passenger cars with a 114 mm filter housing

Performance Benefits

By maintaining clean oil, the W 820 helps to:

• Reduce engine wear – keeping abrasive particles out of critical components.
• Improve fuel efficiency – by ensuring optimal oil viscosity and flow.
• Extend service intervals – due to its high filtration capacity and durability.
• Protect catalytic converters – preventing contamination that could damage emission control systems.

Installing the MANN‑FILTER Oil Filter W 820 is straightforward:

1. Drain the engine oil completely to avoid cross‑contamination.
2. Remove the old filter by unscrewing it counterclockwise.
3. Clean the filter mounting surface with a lint‑free cloth.
4. Apply a thin layer of fresh oil on the new filter’s gasket to ensure an airtight seal.
5. Screw the filter clockwise until snug, then give an additional 1/4 turn for a secure fit.
6. Refill the engine with the recommended oil type and quantity.

Always consult your vehicle’s service manual for specific torque specifications and oil change intervals.

The W 820 is manufactured in a controlled environment that adheres to MANN‑FILTER’s strict quality standards. Each filter undergoes rigorous testing, including:

• Pressure drop measurement – ensuring minimal resistance to oil flow.
• Contaminant retention test – verifying the filter’s ability to capture fine particles.
• Durability assessment – subjecting the filter to temperature and pressure cycles.

MANN‑FILTER is a globally recognized brand known for its commitment to innovation, reliability, and environmental responsibility. The Oil Filter W 820 reflects this heritage by combining advanced filtration technology with user‑friendly design.
