Air Filters
Drop-in performance air filters for Porsche. Washable, reusable OE-replacement elements that fit the factory airbox with no modification and outflow the disposable paper filter they replace.
Two media types run through this catalog and the difference matters. Pro 5R is oiled cotton gauze — the highest airflow available in a drop-in filter, cleaned and re-oiled at service intervals. Pro DRY S is dry synthetic — slightly less airflow, no oil at any point, wash and dry only. Every listing states its media in the title, along with whether the part number ships as a single filter or a set of two.
