K&N does that too, and used oil analysis from K&N engines don't impress me. Do you have used oil analysis from AIRAID equipped engines?

The kinds of tests you ask for have never been done. "Best" is also very subjective because to one person it might mean maximum flow and another it might mean filtration efficiency. You need to define what "best" is for you.

Basically, all the name brand filters are within the range of "good" meaning they will meet or exceed the OEM requirements. Some brands, or individual part numbers, might be a few ticks better in some way than another but in order to find out, you'd either need to get the specs from the manufacturers of the filter brands and part numbers you are interested in or pay for independent testing. You are more likely to find testing done on aftermarket performance filters than OEM replacements.

Nothing wrong with Fram air filters as a brand IMO based on quality of construction.

No, I don't have used oil analysis using AIRAID filters, sorry.

I have a Fram AirHog in my car and I can notice quite a bit of difference in acceleration
and idle quality between it and a standard paper filter. I'd recommend a Fram AirHog,
but they're no longer available. AIRAID is the closest product I found.

imho, the "best" depends on the conditions you drive in. the key is cleaning or changing when needed. i use oem and change if needed after a visual inspection each time i change the oil.

I'm not a fan of the construction of Fram oil filters but I do like their air filters. They are less than $6 at walmart for my cars.

+1 Fram air filters run fine by me

For imports: factory OE filters made by Denso or Toyo Roki are the best by far.
