MMX Magnetic Sump Plug / Magnetised Oil Drain Bolt for BMW & MINI (Excluding S55) | OEM-Style Replacement

Upgrade your lubrication system with a magnetised drain bolt for BMW and MINI

Give your engine the protection it deserves. This high-strength magnetised oil pan drain bolt captures microscopic ferrous debris and swarf that circulates during normal use, helping to keep your lubricant cleaner for longer and reducing wear on bearings, pumps and journals. It is a smart, low-cost preventative maintenance upgrade for road, track and tuned cars alike. Does not fit BMW S55.

Every heat cycle and every hard pull can shed tiny metal particles. By attracting and holding those particles at the lowest point of the sump, this mag plug helps minimise abrasive contamination, supports more consistent oil pressure and promotes smoother operation between services. We run these on our own builds and our customers love the extra peace of mind.

Why choose this magnetised drain bolt

• Captures metal filings and ferrous particles before they circulate
• Helps reduce engine wear and extend component longevity
• Simple OEM-style replacement for the factory drain bolt
• Ideal for remapped, track day and performance-focused vehicles
• Quick install at your next oil change and reusable service after service
• Works with fully synthetic, semi-synthetic and mineral oils

Compatibility

Designed for widespread use across BMW and MINI petrol and diesel platforms. Not compatible with S55-powered models. If you are unsure about fitment, contact us and we will be happy to help.
