K&N 33-2181 Air Filter Set for Mercedes GL-Class X164 – GL450 GL500 GL550 (Set of 2)

Pair of K&N 33-2181 washable, reusable high-flow drop-in air filters for the X164 GL-Class. Layered oiled cotton gauze media replaces the disposable paper element — more airflow, and the last filter the vehicle will need.

Your GL takes two. The X164 runs a twin-airbox layout, so this listing is a matched pair.
