spin-on oil filter, Chrome or Black Fits: > 17-21 M8

This is an OEM style replacement for the oil filter that was updated by H-D in 2020. This filter features a longer body (early is 89mm/3.5", new is 102mm/4") and holds 25% more filtering media surface to better support the higher oil flow in M8 engines. The 5-micron filtering media is otherwise identical to the earlier 63798-99A (chrome) and 63731-99A (black) filter it replaces. The early filter is still advised for Twin Cam models, this longer late style filter is advised for all M8 engines.
