In essence in the real world, which has a dynamic atmosphere all this is arbitrary. Manufacturers don't put things like filters in because they are the best they can possibly manufacturer they are on there because the accountants agree that it is at the right price. Case in point, my brother worked for the largest Jeep dealership on the East Coast and he said in order to go from the standard dashboard to a leather dashboard on that vehicle it would have cost the manufacturer 50 cents more per vehicle, they didn't do it, it's an option. All the people I rode with used K&N, they still do, these are guys that do their own work on their bikes. All I know is I change them every time, don't reoil, and it costs me a little more money. The bike runs great, she breathes fine, and now with the Torq Loopz even better. A lid for every pot
So that's the problem! The indoor temperature and humidity in that lab caused the K&N filter to let 43 TIMES MORE DIRT pass through than a paper filter. I'm sure that out there in the 'real world', a K&N works much better. Just make sure you don't ride indoors!
