Original MANN-FILTER Oil filter W 921/80 – For Passenger Cars

MANN‑FILTER Oil Filter W 921/80

The MANN‑FILTER Oil Filter W 921/80 is a high‑performance filtration solution engineered specifically for passenger cars that demand reliable engine protection and optimal oil circulation. Designed with precision engineering, this filter delivers superior contaminant removal while maintaining low resistance to flow, ensuring your engine receives clean oil at all operating conditions.

Key Features & Benefits

• Advanced Filtration Media: Utilises a multi‑layered filtration core that captures particles as small as 0.5 µm, protecting the engine from wear and extending service life.
• Low Pressure Drop: Engineered to minimise resistance, which improves fuel efficiency and reduces strain on the oil pump.
• Durable Construction: Made with high‑grade polypropylene housing that resists cracking and deformation under temperature extremes.
• Anti‑Return Valve: Integrated valve prevents backflow of contaminated oil, maintaining filter integrity throughout its service life.
• Universal Fitment: Designed for a wide range of passenger cars, including models from Opel, Mitsubishi, Isuzu, and many others.

Technical Specifications

Installation & Maintenance

Installing the MANN‑FILTER Oil Filter W 921/80 is straightforward:

1. Turn off the engine and allow it to cool.
2. Locate the existing oil filter housing on the engine block.
3. Unscrew the old filter using a suitable wrench.
4. Clean the mounting surface with a lint‑free cloth.
5. Apply a thin layer of fresh oil to the rubber seal of the new filter.
6. Screw the new filter clockwise until it is snug but not over‑tightened.
7. Check for leaks and start the engine to ensure proper operation.

For optimal performance, replace the filter at every oil change interval recommended by your vehicle manufacturer. The anti‑return valve ensures that once installed, the filter remains sealed against backflow, reducing maintenance frequency.

Performance Highlights

• Extended Engine Life: By trapping fine particles and preventing sludge formation, the filter protects bearings, pistons, and camshafts from premature wear.
• Improved Fuel Economy: Low pressure drop translates to less energy required by the oil pump, contributing to overall vehicle efficiency.
• Consistent Oil Quality: Maintains optimal viscosity and cleanliness throughout the engine’s operating range.

Compatibility Overview

The MANN‑FILTER W 921/80 is engineered to fit a broad spectrum of passenger vehicles. Below are some representative models that commonly use this filter:

• Opel Astra, Corsa, and Insignia series
