Re: Air Filter Size (Hopefully last filter question!)
A regular paper filter is just that, a solid piece of paper. Not air tight but not easy to breath thru either. The K&N filters are a gauze material like a hospital bangage. Obviosly a lot more air can pass thru this than paper. However the gauze isn't as good at keeping out tiny particles, this is where the K&N oil comes into play. Because it just wets the gauze, it still allows gobs of air thru, but the oil always remains tacky and this is what traps the particles. A lot more dirt sticks to the tacky oil that does the paper. Get the K&N, you'll be happy.
