Couple of great oil filter reviews online if you Google "oil filter review", but they're all a couple years outdated now.
Amsoil and Wix seem to do well.
While Fram never earns high marks it's easier to find and I've yet to have a problem with the premium Frams. YMMV.
I've been using x2 as of late, and I'm seriously considering a high-end bypass system with remote-mounted filter just to see how well it performs. Haven't decided on the brand yet.
