MANN-FILTER W 940/66 Oil Filter
The W 940/66 oil filter is a product of the renowned MANN-FILTER brand, designed for effective engine oil purification in both commercial and passenger vehicles. Thanks to its advanced design, the filter effectively traps contaminants generated during engine operation, protecting the lubrication system from premature wear.

Key Features of the W 940/66 Filter:
– High filtration efficiency – the use of advanced filter media ensures effective retention of solid particles such as metal shavings, carbon deposits, and soot.
– Durable housing – a robust metal construction resistant to high pressure and temperature variations typical of internal combustion engine operation.
– Anti-drainback and bypass valves – ensure continuous oil flow even under harsh cold-start conditions or when the filter is partially clogged.
– OE-quality standard – meets or exceeds the requirements of vehicle manufacturers, which is why it is also used as original equipment.

Why Replace the W 940/66 Oil Filter Regularly?
Contaminants entering the lubrication system are harmful to engine component surfaces. When the filter loses its flow capacity, the oil is no longer properly purified, which leads to:
– Increased friction and wear on engine components,
– Elevated operating temperatures,
– Reduced lubrication quality,
– Higher risk of turbocharger or bearing failure.

Regular oil filter replacement – ideally with every oil change – significantly reduces the risk of serious engine issues and extends engine lifespan.

Applications of the W 940/66 Filter:
This filter is used in a wide range of diesel-powered vehicles, including delivery vans, trucks, agricultural machinery, and some passenger cars. Before purchasing, always verify compatibility with the specific engine model and OE number.
