Cabin Filter

This is an OEM equivalent cabin air filter. Dirt, pollen, and leaves can easily build up and cause the air conditioning and heating system strain. Subaru recommends replacement every 15k miles on most vehicles equipped with these filters standard (model years 2005 and newer). 

NOTE: Subaru is not terribly clear on what years and models before 2005 had filters or spots for them from the factory. We advise you look for a replacement sticker on the door jamb or remove glovebox to verify you have one or the space for one on pre-20005 models.
