Fuel and air are the essential ingredients for engine combustion. And modern diesel engines require impeccably clean air in order to breathe. This presents a huge challenge at many worksites, where dust, sand, moisture, soot, pollen and many other substances are constantly present. Without adequate filtration, engine performance will undoubtedly suffer. There’s only one way to ensure optimum protection in the harsh conditions and remote locations where MTU engines work: genuine MTU air filters.
