I tried to order the green Mazdaspeed 1.3 bar radiator cap today from Cork Sport but they called to let me know that it will not work on the Mazda Miata. Apparently the green radiator cap only works on some newer Proteges with the Calsonic radiator. The Miata uses a Nippondenso radiator which has a different style neck. According to Cork Sport the only Mazdaspeed radiator cap compatible with the Miata is the one with the pink sticker on top.
