MMX BMW Magnetic Sump Plug / Engine Oil Drain Bolt – M12x1.5 Oil Pan Bung, 6061‑T6 (T6061) Aluminium, Safety‑Wire/Lockwire Drilled, Sealing Washer Included

BMW M12x1.5 Magnetised Drain Bolt - T6061 Aluminium - Lockwire Hole - Sealing Washer Included

Keep your engine healthier for longer with this high-strength magnetised sump bolt designed for BMW applications that use the M12 x 1.5 thread size. The powerful embedded magnet pulls in ferrous swarf, tiny metal filings and microscopic debris from the oil, helping to minimise wear on bearings, journals and other precision internals. It is a simple, low-cost upgrade that supports cleaner servicing whether you daily drive, enjoy fast-road running or head out on track.

We run this mag plug on our own cars and our customers regularly report noticeably cleaner oil changes and confidence-inspiring inspections. If you want a quick, smart way to support engine longevity and preventative maintenance, this is a must-have servicing upgrade.

Highlights

• High-strength magnet captures ferrous contaminants for cleaner lubrication and reduced wear
• T6061 aluminium body for a strong, lightweight, corrosion-resistant upgrade over standard hardware
• Pre-drilled head for lockwire use in motorsport or harsh conditions to resist loosening
• Direct drop-in replacement for the factory drain bung on compatible BMW oil pans
• Reusable at each service - simply wipe the magnet clean during an oil change
• Includes an aluminium sealing washer for a reliable, leak-resistant seal

Fitment

Suits BMW engines with an M12 x 1.5 sump thread.

• Not suitable for B58 engines due to the internal baffle arrangement
• Not suitable for N13 engines as they use a different thread size

Unsure about compatibility or thread pitch on your specific model. Contact us and we will confirm fitment before you order.

Why a magnetised drain bolt helps

Standard filtration can miss ultra-fine ferrous particles that circulate after normal wear and tear. By placing a strong magnet at the lowest point in the oil pan, this plug attracts and holds those particles so they can be removed at the next service. The result is cleaner oil, less contamination recirculating through critical clearances and greater confidence in the health of your engine between interval checks.

Installation and servicing

Fits in place of the original drain screw during a routine oil change. Tighten to the manufacturer torque specification for your engine and replace or clean the sealing washer as required. At every oil service, wipe the magnet clean before refitting.
