The MMX Performance BMW Magnetic Diff Plug is a simple, cost effective upgrade that can dramatically increase your differential's lifespan. As the differential wears, tiny metallic particles become suspended in the oil - our magnetic diff plugs help to safely separate these nasty particles out of your lubricants.
This will fit all differentials that use a thread of M22x1.5.
