The MMR Performance magnetic diff plug is a simple, yet efficient tool that can dramatically increase your differential's lifespan. ​ 

Designed to keep metal particles away from important mechanic moving parts. The magnet can be cleaned off when diff oil is changed as part of routine maintenance.

A direct replacement for the OE part, the MMR Performance magnetic diff plug is produced from T6061 lightweight aluminium and is anodised.
