The best engine protection

Wünscher Oil filters have the following advantages:

• Functional reliability during the entire service interval
• maximum separation efficiency
• low flow resistance
• easy to fit and permanent 100 % tightness
• high quality extruded gasket with shore hardness 75
• special paper embossing for high fold stability
• durable corrosion protected body
• optimum protection for the engine
• Anti-Drain valve and/or Bypass valve according to OEM

 

The oil circuit is of central importance, because only clean engine oil can ensure a smooth consistent engine performance. If the circulating oil is not permanently purged from dirt particles and combustion residues, protection against wear is no longer guaranteed. In the worst case even engine failure is possible. Thanks to german quality in production, design and process control, Wünscher filters are up to the tough requirements of current vehicles.

Naturally water is the worst enemy of all vehicle engines but also filters need to cope with water. While Oil is burned the oil absorbs increasing ammounts of Water. The advanced water-unsolveable filter media impregnation protects the filter from water and humidity. Due this technology paper integrity, performance and structural stiffness can be ensured over the enitre livetime of the filter.

Excellent fit guarenteed

Our Filters are designed for modern high-performance oils and master even the most demanding technical challenges confidently. Since the fields of application of oil filters and the requirements placed on them are different, there are Wünscher oil filters in various designs.

The great Wünscher know-how is particularly evident in the details:

Anti-drain valve:

• Ensures that filters and oil ducts do not run idle when the engine is off and that a quick oil supply is ensured when starting the engine.

Bypass valve:

• Ensures oil supply during cold start phases and when the replacement interval is significantly exceeded if the oil filter is very dirty.

Filtration Material:

• Thanks to outstanding dirt holding capacity and high material resistance each filter is perfectly matched to the respective vehicle model

Especially when driving in challenging conditions - such as uphill, with heavy load, with diesel fuel and a downsized engine - the frictions inside the engine leeds to high engine oil degeneration and engine abrasion formation. Therefore oil filters are exposed to temperature endurance loads of up to 135°C. This leads to aging and embrittlement of the filter paper. To ensure that the engine does not run out of clean oil the oil filter must be replaced at regular intervals. The service interval is provided by the vehicle manufacturer and should be done on an regular basis.

Our online catalogue offers the right oil filter for almost every application (car, truck).
