Intake Filter Question

New to the forum and pretty new to the Diesel world. I have a 97 f250 and was preparing to buy an AFE stage to intake system. I know that they sell three different filters and was wondering what the difference between the three. Mostly if the oiled or non oiled are preffered? Thanks

Non-oiled is the preferred filter (white one). The other two (blue and yellow) are oiled and offer two levels of filtration. Oil is not preferred mostly because the new filters are hosed with excess oil that will stick to your turbo impeller lowering it's efficiency. Cleaning a filter brings with it the potential for damage that will let dust through. Dust kills engines. Then there is the cost, AFE is an expensive system. Lots of people like them, I had one, but the Tylmar style intake is less than $100 if you buy a kit, refills are $30, and the filters can be bought at any parts store with a couple hours notice to them. I ended up changing to a Tylmar intake because the AFE was too expensive to maintain over the long haul.

I like my non oiled (blue) afe filter, but the filter is kind of costly, I replace maybe every 6 months to a year, but also you could use the afe intake system with the tymar filter/donaldson
