If you want to play it safe when choosing an oil filter, choose MANN-FILTER. They are designed for modern high-performance oils and can stand up to even the most demanding technical challenges. As the application areas of oil filters and the demands placed on them vary, MANN-FILTER oil filters are available in different designs.

Mann-Filter – Cartridge Oil Filter: Ideal For Any Type of Oil (Part No.HU 6013 Z)

More and more performance, less and less consumption – in order to meet the high demands placed on modern engines, automobile manufacturers demand the absolute highest levels of performance from the engine components used.

If the circulating oil is not permanently freed of impurities and combustion residues, protection from wear is no longer guaranteed. In the worst case, this may even damage the engine. If you want to play it safe when choosing an oil filter, choose MANN-FILTER. They are designed for modern high-performance oils and can stand up to even the most demanding technical challenges. As the application areas of oil filters and the demands placed on them vary, MANN-FILTER oil filters are available in different designs.

Product Features:
  • Outstanding dirt holding capacity
