I agree with this 100%. Oiled filters allow too much dust into the intake air, and the oil that gets stripped off isn’t good for the turbos. I haven’t found a better filter media than Donaldson. The 6” diameter filter on their Raptor kit seems a bit small for the twin turbo setup, the one in my Cummins truck is 8”.

The stock filter on the F-250 diesel trucks was (and may still be) made by Donaldson. If possible I’ll look into retrofitting one of those as they are good sized.
I was going to add this. Some oiled and dry filters “flow” more because they filter less. In any vehicle I ever ran with an oiled, if you take the filter off after so many miles, you’ll notice there is a buildup of fine particulates on the inside of the intake tract.
