Any info on these? I happened to walk by them at Lowe's, took a quick look in a box and noticed that the end of the filter is covered in plastic, which I thought was a nice touch. All I've been able to find online is that they're sold by Old World Industries, same people that sell Peak antifreeze and Herculiner bedliners. I didn't buy one (although I was tempted) since I've stockpiled a nice supply of filters already. I did a search here and nothing came up, so if I missed something, point me to the thread. Thanks. Their site.
