Myth 4

Unlike with oil filters, the quality of air filters is not an issue – they are more or less all the same and are not as important for the running of the car. You can opt for the bottom price range without any problem.

Wrong! Consider the facts:

Oil filters are usually highlighted and attract attention. However, the importance of the air filter has increased enormously in modern vehicles. Reasons why you shouldn’t skimp on this:

• modern engines are becoming increasingly efficient and are therefore making ever higher demands on air filters

• with the increase in the air volume passing through the filter, both the load on the air filter and its importance have risen proportionately

• an efficient air filter is the basis for optimum fuel combustion

• if water enters the air filter housing (as a result of heavy rain, for example), the correct function of simple air filters can no longer be guaranteed, which leads to a drop in engine power

• a flame-retardant impregnation protects both engine and occupants.
