Original MANN-FILTER Oil filter W 917/1 – For Passenger Cars

MANN‑FILTER Oil Filter W 917/1

The MANN‑FILTER Oil Filter W 917/1 is a premium engine oil filtration solution designed for passenger cars that demand reliable protection and optimal performance. Crafted with precision engineering, this filter delivers superior contaminant removal while maintaining low pressure drop, ensuring your engine receives clean oil at all operating conditions.

Key Features

• High‑Efficiency Filtration: Utilises a multi‑layer media system that captures particles as small as 0.5 µm, protecting pistons, bearings, and camshafts from wear.
• Anti‑Return Valve: Integrated valve prevents oil backflow during engine shutdown or low‑speed operation, preserving filtration integrity.
• Robust Construction: Made from durable polypropylene housing with a reinforced gasket seal to withstand high temperatures and pressure variations.
• Low Pressure Drop: Engineered for minimal resistance, which translates into better fuel economy and reduced engine load.
• Wide Compatibility: Suitable for a broad range of passenger car engines, including many models from major manufacturers that require the W 917/1 specification.

Design & Engineering Excellence

The filter’s design incorporates a three‑stage filtration process. The first stage captures large debris such as dirt and metal shavings. The second stage targets fine particles, while the third stage ensures that only sub‑micron contaminants are removed before oil reaches the engine. This layered approach guarantees consistent performance over extended service intervals.

Its anti‑return valve is strategically positioned to block reverse flow without compromising forward pressure. During normal operation, the valve remains closed, allowing oil to pass freely. When the engine stops or operates at low RPM, the valve opens, preventing any backflow that could introduce contaminants into the filter media.

Installation & Maintenance

Installing the MANN‑FILTER Oil Filter W 917/1 is straightforward. The filter uses a standard M20 × 1.5 thread size, making it compatible with most passenger car oil filter housings. A simple hand-tightening procedure ensures a secure seal; no special tools are required.

For optimal longevity, replace the filter at recommended intervals or when oil quality degrades. The filter’s robust gasket and anti‑return valve design reduce the risk of leaks, providing peace of mind during routine maintenance.

Performance Benefits

• Engine Longevity: By removing harmful particles, the filter protects critical engine components from premature wear.
• Fuel Efficiency: Low pressure drop reduces engine load, contributing to better fuel economy.
• Consistent Oil Quality: Maintains stable oil viscosity and temperature characteristics, which is essential for high‑performance engines.
• Reduced Emissions: Cleaner oil flow helps the catalytic converter operate more efficiently, lowering exhaust emissions.

Applications

The MANN‑FILTER Oil Filter W 917/1 is engineered for a wide array of passenger car engines. It is commonly used in models that require the W 917/1 specification, ensuring compatibility with both domestic and international vehicle platforms.
