Sixspeed,
If you are going to use the "Duel-remote" (BMK-15) By-pass, you will have to use the SDF-26 ("Full-Flow") and the BE-100 ("By-Pass")that come with the kit. If you elect to use the "Single-Remote" (BMK-11) By-pass Mount, you can use any "Full-flow" element at the OEM location, including the "Fleetgaurd" The "Full-Flow" element that Amsoil produces is the SDF-80, and it too can be used at the OEM location on engine block.
Hope this helps,
Wayne
