Protect your final drive the smart way. This ECS magnetic diff bolt captures ferrous particles during every axle oil change, helping keep your BMW or MINI drivetrain silky smooth while providing an early warning of wear.
Built around the popular M22 x 1.5 thread with a 14 mm hex key drive, this magnetic drain bolt is a simple, cost-effective upgrade for routine driveline servicing. The high-strength magnet traps steel swarf from gears and bearings so it is not recirculated in your gear oil, supporting longer component life and cleaner fluid between services. Ideal for fast-road, track-day and daily use where reliability matters.
