Masuma oil filters are produced in exact accordance with the factory specifications for OEM filters. The filter element is a high-density folded paper block. The filter design includes two crucial valves: the anti drain (check) valve, which protects the engine from oil starvation at start-up, and the bypass valve, which ensures direct oil supply in situations, when the oil can't be pumped through the filter. Masuma oil filters ensure complete oil purification from solid particles, sludge and wearing products, which can be harmful for the rubbing engine parts.
