For the cabin microfilter, we access the housing, verify the airflow direction and seal integrity, and fit the correct OEM microfilter element. Before closing up, we perform a visual intake and MAF sensor check and clear any debris in the housings. We’ll note filter condition on your repair order and discuss timing for future checks based on your driving. Ready to go? Schedule service online today.
