The magnetic oil drain plug from JMP (M12 x 1.50 mm, 15 mm, aluminum racing, black) makes a very high-quality impression. The workmanship is top-notch, the aluminium looks stable and cleanly anodized, and the magnet at the tip sits firmly and strongly - just as you would expect from a racing part. Especially with regular maintenance or an ambitious driving style, a magnet like this is really useful for detecting metal abrasion in the oil at an early stage and preventing damage.
The screw would have fitted perfectly on my Yamaha MT-03 (built in 2016) - thread fits, length fits, everything is great.
Unfortunately, I still had to return it because no sealing ring was supplied. Although this is not misrepresented in the item description, I honestly expected a suitable copper or aluminum sealing ring to be included with such a product - especially because it is a safety-relevant part and most other suppliers supply the ring directly. Without a suitable sealing ring, I would either have had to improvise or order an extra one.
Conclusion: Top quality, looks great, magnetic function very useful - but make sure when buying that no sealing ring is included. If you order one separately or still have one at home, the screw is highly recommended!
Have used these gaskets for the valve cover screws and they do exactly what they are supposed to. They seal tight, keep oil in and seem like a definite improvement over worn original gaskets. Installation was easy and the material feels both resilient and durable. No signs of oil sweat after installation - completely satisfied!
