I DK how much these particle levels matter, but the first vid does a good job of showing that these minor diffs in air flow are negligible for performance. I'd love to see a similar (or perhaps better-designed) comparison for the other high perf filters. The fixation upon filter flow comes from the naturally aspirated world, especially with carbs; our cars have a nice big turbo that is being told how much air to push - I suspect it is automatically compensating for any restrictions the same as for higher elevations, and just pushing a little harder.

Thanks for posting this. I'm definitely going to take this into consideration and replace my K&N filter.
