I'm a fan of oil bath air filters and always feel a twinge when I see another converted to dry elements. They are extremely efficient and though they can be a bit of a pain to clean, most of us would only end up having to do it once every 5-15 years. Take a look at serious road construction equipment and you'll see that oil bath predominates still. The reason is that they can take extreme loading of dirt without suffering restriction to air flow. Unlike dry elements where the dirt is trapped directly in the element and thus slowly closes off the paths for air flow, in the oil bath most of the dirt is captured in the oil before the air flow ever reaches the filter media (usually oiled kapok fiber), hence you maintain less restrictive breathing over longer intervals. A very clever design.
