It is not necessary to clean or wash the element.

Replacing the air cleaner element

Replace the air cleaner element according to the maintenance schedule in the “Warranty and Maintenance Booklet”. Under extremely dusty conditions, replace it more frequently. It is recommended that you always use genuine SUBARU parts.
