Please search Fumoto Valve 106S. My search results give me the local sellers, which is not useful for you and everyone else. EDIT: https://a.co/d/02PPY2ML Here is the Amazon link. This one is slightly different from what I have, but I also bought this by mistake. What is important is, it should be M14 by 1.5 thread pitch. https://www.mazda6club.com/posts/5101635/ Here is how I did it. I mean, how I changed my oil with that valve installed. Included is the tutorial on how to reset the oil change interval reminder.
