Big Bike Parts Magnetic Drain Plug

• Magnets attract and hold ferrous metal particles that are floating around in your engine

• At fluid / oil change time you can inspect the plug for ferrous metals in your oil

• Having ferrous metal on the magnet can be an indicator of an impending problem of cams, rings, rods or shafts that may need servicing

• In most cases an oil analysis can tell you what type of metal and what it is from, pointing you in the correct direction
