MANN‑FILTER Oil Filter W 815/81 – For Passenger Cars

The MANN‑FILTER Oil Filter W 815/81 is a high‑performance filtration solution designed specifically for passenger cars that demand reliable engine protection and optimal oil flow. Crafted with precision engineering, this filter delivers superior contaminant removal while maintaining low resistance to ensure your engine runs smoothly under all driving conditions.

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.
• Low Pressure Drop: Engineered to minimise resistance, preserving fuel efficiency and maintaining optimal oil pressure throughout the lubrication circuit.
• Durable Construction: Made with high‑quality polypropylene housing that resists corrosion, temperature extremes, and mechanical stress.
• Anti‑Return Valve: Integrated valve prevents backflow of contaminated oil, ensuring consistent filtration performance even during rapid engine deceleration or idling.
• Universal Fitment: Designed to fit a wide range of passenger car models, including popular brands such as Honda, Rover, Triumph, and many others. The filter’s dimensions (M22 × 1.5 thread) are compatible with most standard oil filter housings.
• Easy Installation: Screw‑on design allows for quick replacement without the need for special tools or additional components.

Technical Specifications

Installation Guide

1. Preparation: Warm the engine to operating temperature. Drain a small amount of oil to relieve pressure.
2. Remove Old Filter: Unscrew the existing filter using an appropriate wrench or by hand if it is loose enough. Allow any residual oil to drain into a container.
3. Clean Housing: Wipe the filter housing with a clean rag to remove debris and old gasket material.
4. Install New Filter: Place the new MANN‑FILTER W 815/81 into the housing, ensuring it sits flush. Hand‑tighten until snug, then give an additional quarter turn with a wrench if necessary.
5. Check for Leaks: Start the engine and observe the filter area for any oil seepage. Tighten further only if leaks persist.
6. Dispose of Old Filter Properly: Recycle or dispose of the used filter according to local regulations.

Maintenance & Longevity

The MANN‑FILTER W 815/81 is engineered for durability, but regular oil changes remain essential. Replace the filter at each oil change interval recommended by your vehicle manufacturer to maintain peak engine performance and protection.
