Original MANN-FILTER Oil filter W 930/21 – For Passenger Cars

MANN‑FILTER Oil Filter W 930/21

The MANN‑FILTER Oil Filter W 930/21 is a premium filtration solution engineered for passenger cars that demand the highest level of engine protection and performance. Designed with precision engineering, this filter delivers superior contaminant removal while maintaining optimal oil flow, ensuring your vehicle’s engine stays clean, cool, and efficient.

Key Features & Benefits

• Advanced Filtration Technology: Utilises a multi‑layer media system that captures particles as small as 0.5 µm, protecting the engine from wear and extending service life.
• High Flow Capacity: Engineered to minimise pressure drop, this filter allows oil to circulate freely, preserving fuel economy and performance.
• Durable Construction: Made with a robust polypropylene housing that resists cracking and deformation under high temperatures and pressures.
• Anti‑Return Valve: Integrated valve prevents backflow of contaminated oil into the engine, maintaining clean oil supply at all times.
• Universal Fitment: Compatible with a wide range of Volkswagen, Audi, Skoda, and Passat models, including various engine sizes and configurations.

Compatibility Overview

The filter is specifically tailored for passenger cars across several major European brands. Below is an exhaustive list of compatible vehicles:

• Volkswagen: Passat (3B2, 3B3, 3B5, 3B6), Golf, Jetta, Polo, and more.
• Audi: A4, A6, Allroad C5, Avant, and other models with 3/4‑16 UNF fittings.
• Skoda: Octavia, Superb, Fabia, and related variants.
• Other European passenger cars that use the standard 3/4‑16 UNF threaded oil filter connection.

Installation & Maintenance

Installing the MANN‑FILTER Oil Filter W 930/21 is straightforward:

1. Drain the engine oil completely to avoid contamination during installation.
2. Remove the old filter by loosening the threaded connection with a suitable wrench.
3. Clean the mounting surface and apply a thin layer of fresh oil to the gasket for a proper seal.
4. Screw in the new filter clockwise until it is snug, then give an additional quarter turn to ensure a tight fit.
5. Refill the engine with the recommended oil type and quantity.

For optimal performance, replace the filter every 10,000–15,000 km or as specified by your vehicle’s maintenance schedule. Regular replacement prevents sludge buildup and maintains engine efficiency.
