The frequency of replacing the air filter element is 10 thousand kilometers.
If you drive frequently on dusty roads, you need to change the filter element more often.
If the filter is very dirty, it has an increased resistance to the passage of air, causes excessive enrichment of the fuel and therefore reduces engine power.
Periodically, you need to remove the filter element and clean it of dust by vigorously shaking it or blowing it with compressed air in the direction opposite to the air movement during engine operation.
