I've been in the equipment repair business all my life and though I can't name all the different sources I've read that said the oil bath filter was better I can tell you that there have been quite a few. Not to mention the observations I've made in the field when opening intakes and intake piping of the different type systems. In an oil bath filter that is properly maintained ALL the air entering the engine actually passes through the oil, hence the name "oil bath". In doing so the heavier dirt particles get slowed down enough by the oil to drop out of the air stream and settle to the bottom of the oil. Too the oil vapor that developes in the inlet neck will coat the incoming dirt particles with oil making them sticky so they cling to each other which makes them heavier and easier to settle out when they acutually get into the oil, or they stick to the walls of the inlet so they never make it into the bath at all. In an oil bath air cleaner the "micron rating" is essentially zero because the air is actually sucked through the oil. Now take your typical paper or foam element type air filter and see what the micron rating on one of them is. Have you heard that as they get dirty they become less effecient but they provide cleaner air? This is because as they get dirty the holes in the paper cloes up due to the dirt particles they catch so they can catch progressivly smaller particles til the close completely off. So, basically with a paper element filter it will only filter the portion of the air/debris/dust that falls below a certain micron rating while the oil bath filters EVERYTHING. True the paper elements get the air fairely clean and you might not actually notice that much difference in the life of the engine, but if you've already got the best system on the market, why back up?
