Another factory weakness is the stock oil filter adapter and its oil filter bypass assembly. Back when these engines were designed, oil filters had no internal bypass and could blow off when the engine was cold and oil pressure was high. The solution was the bypass that sent unfiltered oil back into the engine. Not good. Filters were also smaller and less efficient in terms of total flow. The Tri-Flow external filter/oil relocation plate eliminated the bypass entirely and picks up oil directly from the Milodon pan. It also allows you to use a single- or dual-Fram PH8A. If you don't have a Milodon pan, Bulltear offers the 626 plate to replace the oil filter adapter.
