So Like most here I ran the Toyota oil Filters until they stopped making the larger version. Then i switched to the WIX(Napa Gold) series which I have always used on my Diesel rigs(Cummins, and Isuzu/Duramax). Recently there was a post on MUD about the WIX filters having valve problems causing loss of oil pressure... I'm not sure if anybody here is aware of this but just wanted to put it out there. Think I'll switch back to the small Toyota filter now....
