Just throwing this out there for you guys!! I was chatting with my parts guy and he informed me that the Wix and Amsoil filters are either built identical or they are made by the same company. So either Wix makes filters for Amsoil or Amsoil makes Wix filters, I would imagin it is the first scenario. It may be a BS marketing scheme but I have heard it a few times. I guess either way your looking at a great filter from Wix :thumbsup:crb8686 said:You can also buy Wix oil filter from O'Reilly's or NAPA. For all who don't know Wix is one of the highest quality filters you can buy.
