aFe Power Magnum FLOW OE Replacement Air Filter with Pro DRY S Media is a direct drop-in panel filter for the 986 Boxster. It replaces the disposable paper element in the factory airbox and outflows it — with no filter oil involved at any stage.
This is the dry filter. Pro DRY S uses three layers of progressive oil-free synthetic media. It gives up a little peak airflow to the oiled Pro 5R and gives you back a filter you wash, dry and refit. Nothing to over-apply, and nothing that can migrate downstream onto a mass airflow sensor — which on a twenty-year-old Boxster is a sensor you would rather not be replacing. If you want maximum airflow instead, the same filter in oiled cotton gauze is part number 30-10090.
Key Benefits:
- Oil-free Pro DRY S 3-layer progressive synthetic media — no oiling, ever
- Outflows the disposable factory paper filter for improved throttle response
- No filter oil means nothing that can contaminate a mass airflow sensor
- 100% polyurethane frame on all four sides for a long service life
- Progressive bump seal ensures a tight, no-leak seal with no gaskets or sealants
- Washable and reusable for multiple cleaning cycles — wash, dry, refit
Compatible Vehicles:
- Porsche Boxster 1997–2004 — H6-2.5L / 2.7L
Note: Part number 31-10090 is supplied as a single filter. Clean at regular service intervals with aFe's dry-filter cleaner only — never apply filter oil to Pro DRY S media, and let the element dry fully before refitting. aFe states this product does not require a CARB EO number.
Installation Instructions:
Ten minutes with the airbox lid off, and nothing to maintain but a rinse.
