Pair of K&N 33-2181 washable, reusable high-flow drop-in air filters for the Mercedes M273 5.5L V8. Layered oiled cotton gauze media in place of the disposable paper element — more airflow, and the last filter the car will need.

Your car takes two. The M273 uses a twin-airbox layout, so this listing is a matched pair.
