I've ran my origional dryflow filter for 149,000 miles with only two cleanings and the inside of my intake tube is as clean as the day it was installed. I only purchased a new one to simplify cleaning cycles which Ive been slacking on.

Outstanding filter and very durable. I work in the West Texas oil field and it's a very harsh desert climate. The filter performs as advertised and then some. I just bought a replacement filter for my Workhorse system on my 2006 Dodge diesel. After 120k miles the original AEM filter is still filtering like new. Just got a replacement to lessen cleaning time. Great product!!

Truck didn't blow up yet, so I guess it's a good filter!
