MMR Performance | Magnetic differential plug | BMW

At PERON Automotive, we know that protecting drivetrain components is just as important as upgrading them. That’s why we recommend the MMR Performance Magnetic Differential Plug—a simple yet highly effective way to extend the life of your BMW’s differential.

As your diff operates, microscopic metallic particles are shed through natural wear. Left suspended in the oil, these particles accelerate internal wear and reduce longevity. MMR’s magnetic plug actively attracts and traps these particles, helping to keep your diff oil cleaner and your drivetrain healthier.

This is a direct-fit replacement for the factory plug and is compatible with all BMW differentials using an M22 x 1.5 thread.

Key Features:

• Magnetic core captures ferrous particles suspended in diff oil

• Helps prevent accelerated wear and premature differential failure

• Simple, effective, and affordable drivetrain protection

• Direct OE replacement – no modification needed

• Compatible with all BMW differentials with M22 x 1.5 thread

Whether you're maintaining a daily driver or safeguarding a track build, this plug is an easy upgrade that
