Differential Service Kit | ES3449386

Often overlooked, scheduled rear differential service is very important. Over time gear lube breaks down causing bearings and internal components fail. Regular maintenance will keep your vehicle running properly for years to come.

• 1 New Genuine BMW Drain/Fill plugs
• 1 ECS Magnetic Differential Oil Drain Plug
