Using a Magnetic Sump Plug is the best way to trap and remove any metal particles from the engine oil. These Magnetic Sump Plug are no longer put in modern engines due to the high manufacturing costs of magnets, powerful enough to do the job. However, we stock replacement Magnetic Sump Plug in most of the sizes used in today's modern, as well as some Japanese classics, motorcycle engines. Make sure you select the correct size and pitch of thread of your original plug. If you don't get it right, you could do some serious damage.
