Voyager, One test of automotive air filters vs 48 years of work experience on motorcycles with all different types & brands of air filters is not enough to change my opinion when it comes to motorcycle air filters.

Have you also noticed that Uni-Filter brand is the most open pore design of all major brand of oiled foam air filters which I am aware of?

I actually prefer the finer pore OEM or TwinAir or similar which work Very Well with SAE 40 or even 10W40. (Yes, I know the engine oils migrate inside of the air box, but easier clean-out than sticky stuff.)

I really like the Kawasaki road bike & atv fine pored oiled foam filters which have 1/8th inch tall Yellow Hair on their exterior. They should have used that material for all Kawasaki product, IMHO. The Hair reduces plugging of the foam pores, which allows easier air flow and longer service interval. And works very well with engine oils.
