What about AEM dryflow filters? (Fram also offers these under their own name)

I came into one for free and like it for my Jeep, which sees a huge amount of dust when out playing on the weekends. A std filter would need changing after 3000-5000 miles, now I can just clean this one out and I'm good to go. Testing in an off road magazine showed it filtered better than about anything, especially K&N. I've had nothing but good luck with it and have seen no signs of dust making it past in the 45,000 miles or so that I have been using it.
