Naw, that is another Green filter, not THE Green VX crazy is using -

Green Performance filters have a larger flow area on their panel units due to better control of the rubber around the edge (take a look at the K&N filter area around the edges) while still filtering down to 5 microns. I'm surprised she noticed the difference but I have seen the numbers and actual tests and they do flow more than the comparable K&N. Plus GREEN is MEAN.
