The Cusco neodymium magnetic drain bolt for Subaru applications replaces the standard oil drain plug with a magnetized bolt intended to capture ferrous metal particles circulating in the engine oil. It provides a simple, service-friendly measure to help collect metallic debris during oil changes and is specified for Subaru-compatible oil pan threads and fitment where a magnetic drain bolt is appropriate.
