This chart makes it look that way,I saw one that had the Amsoil & K&N at the top but the way that one was worded might explain the different result. The other page I saw (I'll see if I can find it again and post it) only tested and talked about the size of particles the media would catch and said nothing about amount of media or the valve or anything else. This page states about "flawed superior filter" about a couple of them.

Does make me wanna go get a PureOne since I have the Napa Gold on mine and according to this chart thats a bad one. For the price of a filter (even an expensive one) it doesn't pay to go cheap in my opinion.

Thanx for the info.
