To the guy that said they filter AND flow better I say no way. It can't do both. They let more air flow because they DON'T filter as well.
I considered a K&N but I pulled one out of the box and held it up to the light in the store. What I saw were holes in the filter media large enough to pass dirt. A good filter media will pass light evenly but this actually had holes that light was shinning through. No thanks!
Thats what I thought but I did some research on K&N and apparently they were FIRST used back in the late 60s by desert offroad racers and became so popular because they outfiltered the paper filters of the era. I also just read that K&N has won more Baja-Style desert road races than all other filters combined. So I would assume that desert style racing would allow the most dirt to enter the motor but apparently the K&N filters worked better in these conditions according to the readings I just read.
