MMX BMW Magnetic Differential Oil Drain & Filler Plug M22 x 1.5 - Anodised 6061-T6 Aluminium OE Replacement Rear Diff/Final Drive Sump Bolt Bung for BMW Axle & LSD (M22x1.5)

Protect your BMW rear axle with a magnetised drain and filler bung upgrade

Looking for a simple, high impact maintenance mod that helps your back axle last longer and run quieter? This MMX magnetised drain and fill bung in M22 x 1.5 thread is a direct swap for the factory bolts on compatible BMW diffs. Its integrated magnet captures ferrous filings and swarf circulating in the gear oil, helping keep the lubricant cleaner for longer, reducing wear on the crown wheel and pinion, carrier bearings and limited slip clutch packs. Ideal for daily use, fast road builds and track day cars that see hard miles.

Why this upgrade works

• Strong magnet core collects metallic debris to help protect gears and bearings
• Helps reduce noise and friction for smoother, more consistent differential operation
• Simple preventative maintenance at your next oil change with clear benefits at each service
• Precision 6061-T6 aluminium with a tough anodised finish for long term durability
• Direct replacement for M22 x 1.5 threaded drain and filler positions on compatible BMW rear drive units
• Great value reliability upgrade for tuned, road and track BMWs
