Review on Premium Magnetic Oil Drain Plug M18 x 1.5 Black Mishimoto - Boost Engine Protection by Jesse Stewart

m18x1.5 is an oddball even by metric standards. I used this in a generator. I could not match the factory plug threads with any/any gauge I could find. Clasp didn't know what I was talking about as she approached them with a fork. it fits perfectly. One comment said they are plastic, mine has an aluminum body, powerful magnet, metal collar with a rubber liner for sealing. Thank you Mishimoto.
