Mazda Miata NA Oil Funnel

A funnel threaded M35-4 at the bottom. Specifically made for attaching directly to the oil fill port on NA Mazda Miata engines. I made this one for the BP5 1.8L in the 1997 Mazda Miata but it should also fit the B6 1.6L and a large number of other Mazda engines that use this same thread size for the oil filler cap.
