The factory oil pan drain plug does not have a magnet. That leaves possible metal particles free-floating around to do damage. Pacific Performance Engineering's (PPE) Billet Hardened Stainless Steel Oil Drain Plug is a direct replacement and comes equipped with a powerful Neodymium magnet that pulls harmful ferrous metal contaminants from the oil which helps to extend the life of your engine. Comes complete with a safety wire provision and a copper washer for a tight seal.
