K&N Air Filter hoop de do-do, or?
Nothing wrong w/K&N if used w/pre-filter in dusty/sandy environments. I have a Donaldson canister and have used a very large cylinder K&N filter only w/pre-filter for many 100's k miles w/o any issues whatsoever.
IMHO, Pre-filters exist for a reason and the K&N works just fine w/one be it in sandy or dusty environments on any gas, diesel or any other fuel type of vehicle.
I have had issues w/vehicles using panel filter (s) and feel panel filters have no place in any vehicle operated off -road or otherwise.
I agree over oiling any filter could negatively effect an AMM even burn it out.
Marketers are always creating new ways to sway the consumer to their accounts products. Air filter wars have been ongoing as long as I can remember and without warning the consumer to don chest-waders first.
