Thanks Raff. I'll check it out but they may not make it in the 3/4x16 thread our engines need.
The reason for going with one of the higher end filters, like Canton, is the full flow, no bypass aspect, so all the oil is filtered all of the time. However the replacement cartridges are about $15 which is the same price as the full flow Amsoil filters (which supposedly also have a good rep).
