I have a large number of cup wrenches for oil filters. Even using Mazda filters, the MK1 and MK2 filters need three different sizes cup wrenches.
The Mk3 needed two but Mazda have just changed it again and even with about 15 cap wrenches both 14 and 15 flutes it now needs a slightly smaller cup wrench than i have.
Best wishes finding a cup wrench that fits your three wheeler every time!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
