Kia Optima: Air cleaner
It must be replaced when necessary, and should not be cleaned and reused.
Replace the filter according to the Maintenance Schedule.
If the vehicle is operated in extremely dusty or sandy areas, replace the element more often than the usual recommended intervals.
• Do not drive with the air cleaner removed; this will result in excessive engine wear.
• Use a KIA genuine part. Use of non-genuine parts could damage the air flow sensor.
