Gentlemen,
Arizona is pretty dusty so I pulled my air filter out a couple days ago at 4000 miles. The stock filter looked brand new. The CB11 air cleaner is in a very protected enclosure and the two rectangular snorkels face rearward so nothing is ever going to touch that filter but air borne dust. In an area like AZ where the ground is always dry and particulate content in the air is high I still think that filter will be fine at 20k miles. In an area like Ohio or Michigan where the ground isn't often dry and particulate content is low that filter will be good for many years and 30k miles easy.
