Should the Cabin Air Filter and Engine Air Filter Be Replaced During Maintenance? The engine air filter is typically replaced every other maintenance service. Below are the replacement intervals and precautions for filter replacement: Factors Determining Replacement Intervals: Replacement should be based on the vehicle's usage. If you notice a significant drop in engine power, it may indicate that the air filter is no longer effectively filtering, which could lead to cylinder scoring, necessitating immediate replacement. Driving conditions and air quality also play a role. In environments with poor air quality, high humidity, excessive dust, severe smog, or heavy pollen, the replacement interval should be shortened. Precautions for Replacing the Cabin Air Filter: If the airflow from the air conditioning vents is noticeably reduced, the cabin air filter may be clogged. The cleaning frequency depends on road conditions (e.g., dusty roads). Early cleaning is recommended. The cabin air filter must be properly installed in its designated position. Operating the air conditioning without the filter in place can degrade dust resistance and impair air conditioning performance.
