The factory 14mm oil pan drain plug does not have a magnet. That leaves metal particles free-floating around to do damage.
PPE’s Billet Hardened Stainless Steel 14mm 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.
Torque spec: 30-35 lb-ft.
