Dimple Manual Transmission Magnetic Drain Plug - M24x1.5

Gear oil works best when it is uncontaminated. Continuous friction in your transmission creates tiny metal particles that contaminate the oil. These particles are measured in microns (one millionth of a meter: 25 microns = .001). Oil filters catch the particles larger than about 35 microns, but they do not remove the smaller particles. Over time, these metal particles are circulated millions of times, polishing (wearing) down the metal components inside your transmission, shortening it's life. Magnetic drain plugs remove these smaller metal particles.
Dimple™ makes some of the finest magnetic drain plugs on the market. What makes Dimple™ plugs different from other magnetic drain plugs? The magnets. All magnets are not created equal -- Dimple's Black Hole™ high-temperature magnets are the strongest, high-temperature, neodymium magnets in the world. Regular magnets lose magnetism at 175° F; Dimple's neodymium magnets are rated at over 300° F, so they continue to grab those destructive metal particles even when things get hot. In addition, Dimple's magnets degrade at the incredibly slow rate of ½ of 1% every 100 years, so they are guaranteed to work throughout your lifetime. 
Custom made for BMW vehicles, featuring a large 1/2 neodymium magnet rated at 300° F.
