I haven't reviewed Bob's original air filter test but as I remember, his test was similar to Project Farm. You be the judge.
And of course, this will differ with every filter application. But, if you have a GM truck with the same engine as PF then, this answers the curiosity of which is better even without including the FRAM Ultra or e.g., a Denso or SuperTech.
It's a cool test/setup he did...straightforward. Results of course make sense - flow and filtering are inversely proportional. I use a K&N and am glad I don't dump flower on top of it...hahahaha It's a good test but the real-world conditions I drive in are quite a bit different. My UOAs always look fine and my intake track behind the filter is always clean to the touch so clearly, while not filtering as well as a paper filter (duh) it does well enough for me. Also, I dig the 0-60 runs - the K&N works, it's not BS and for those of us tuning/trying to extract as much as we can out of our cars, it matters.
