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!
