The frequency of replacing the air filter element is 10 thousand kilometers.
If you frequently drive on dusty roads, you need to change the filter element more often.
If the filter is heavily contaminated, it has increased resistance to air passage, causes excessive fuel enrichment 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 when the engine is running.
