Way back I had one of those garbage triangle air cleaners because it way laying around from my brothers old high school ride and I had hood clearance issues. One day I bought a K&N stack and pulled the hood off. The car gained 7 tenths.
Industrial stuff, no one is going to take the time to clean a gauze filter. Company buy the filters and pre filters and you throw them on.
My wife used to run my Tundra at the track. The day I put a K&N filter it slowed down a bit. Not sure if it was due to any flow issues or the computer getting weirded out from the new style filter. Put a Denso OEM back on.

In the test, the triangular filter lost about 10%, like 72 HP almost anything is better than one of those. The flipped lid stock MOPAR with a 3 inch paper filter lost 11 HP. The tapered velocity stack design has way more effect at reducing restriction than the media does. The smooth transition into the carb picks up more HP than any media change did.

You really need to watch the dyno test again, instead of calling BS on it.

Mass airflow (MAF) sensors notoriously don't like gauze filters because the oil that gets pulled into them skews the readings going to the computer.

Many chain saws use gauze filters, open one up sometime and see how much sawdust makes it's way into the intake tract.

If you want clean air on a street driven car I would surely avoid a K&N, if you're only drag racing it and air filtration is secondary to performance then I guess you want the K&N, or just delete the filter entirely.

In testing the K&N with flour as a controlled particulate it let in just under 3000 particles, where the conventional Purolator and WIX were under 200 particles. Pick your poison, but I'll never run a gauze filter on anything I want to last.

I did not call BS on any test or video. Never watched it. Just gave my own experiences.
I live in Humboldt County CA. Chainsaw country as it gets. Not unusual for our loggers to have 5'+ chainsaw bars. Some of them are like starting a Volkswagen. Cleaned many chainsaws and sawdust gets past them all. Most seem to be fine plastic screens, Huskys anyway. My preferred brand.
