Crankcase Cap With Magnet – Kawasaki|Yamaha

Magnetic drain plug to help keep the metal from damaging your engine.
When the engine components wear out they begin to release metal shavings into the engine oil.
These plugs have a strong magnet to help collect these debris directly from your oil during operation.
When it comes time to change the oil, just clean the magnetic part.
