Then people replied saying things like "That's all marketing to sell more oiled filters" Instead of arguing and disproving the scientific research. Or replied with "but my buddy got a CEL after using an intake with an oiled filter" while completely ignoring that people get the same CEL on intakes with paper filters.

I don't have the links to the studies on me. I'm sure you can google them to find them (that's how I got them). But I still stand by that oiled filters are the better filter. And I've run oiled filters since 2013 with no issues. Even the times I've cleaned the filters and applied way too much oil before reinstalling them. Though you shouldn't over oil the filter just because less air will be able to pass through it. (air cannot pass through oil) not because it will damage the MAF.
The whole maf oil corruption thing is based on vag cars which are/were highly sensitive to it.
Some of the manufacturers of drop in filters (Eg pipercross) do not oil their filters for vag cars but do oil the exact same media for most others (Eg bmws).
