MMR Performance Magnetic Rear Differential Plug M22x1.5 for BMW & MINI - Anodised T6061 Aluminium Diff Oil Drain Bolt/Fill Screw, Rear Axle Final Drive Magnetic Plug, Swarf Catcher Upgrade for BMW M Series & MINI Cooper S JCW

MMR Performance Magnetic Rear Axle Plug for BMW and MINI

Keep your final drive running smoother for longer with this high‑quality magnetised plug from MMR Performance. Designed to pull metal filings out of your gear oil, it helps protect crown wheel, pinion and bearings, supporting quieter operation and longer component life on BMW and MINI applications that use the M22 x 1.5 thread.

Why it belongs on your car

• Captures ferrous debris and metal dust from the lubricant to help reduce wear
• Large‑face magnet offers excellent surface area for effective particle capture
• T6061 aluminium body with an anodised finish for durability and corrosion resistance
• Direct swap for the factory fill or drain plug on housings using M22 x 1.5
• Simple, affordable preventative maintenance for spirited road and track use

How it works

As the final drive turns, microscopic fragments inevitably circulate in the oil. This magnetised plug attracts and holds those filings so the lubricant can do its job more effectively. At each oil change you will see what has been captured, giving you confidence that contamination is being removed before it can recirculate.

Fitment

Suits BMW and MINI rear differentials using an M22 x 1.5 threaded plug location for either fill or drain. Please verify the thread on your existing plug before ordering.
