BMW Universal Magnetic Engine Oil Sump Drain Plug M12 x 1.5 Thread (Fits E30 / E36 / E39 / E46 / E60 / E70 / E82 / E90 / E92 / F10 / F30 / F80 M3 / F82 M4 / Z3 / Z4 + MINI / Replaces 11137535106 / 11131273093)

Extend the life of your BMW engine with this premium billet aluminum magnetic oil sump drain plug, precision crafted from aircraft-grade 6061-T6 aluminum to capture ferrous metal particles in your engine oil during every oil change. As any BMW engine accumulates miles, microscopic metal particles inevitably suspend in the oil from natural wear of bearings, cam lobes, timing chain components, and other moving parts. These suspended ferrous particles act as abrasive contaminants, accelerating wear of the very components they originated from in a destructive feedback loop. This magnetic drain plug solves the problem by attracting and holding these ferrous particles at the bottom of the oil pan, where they remain captured rather than circulating through the engine. The result is dramatically cleaner oil, reduced internal wear, and extended engine longevity. The drilled body design accepts safety wire for motorsport applications, ensuring the plug cannot loosen even under sustained high-vibration or extreme conditions.

Features:

• Large magnetic end surface area – effectively adsorbs tiny ferrous metal particles suspended in engine oil, separating contaminants for cleaner more efficient lubrication
• Drilled body for safety wire – allows attachment of locking wire to the oil pan for maximum security under motorsport, track, or extreme driving conditions
• Premium 6061-T6 aircraft-grade aluminum construction – delivers exceptional strength while keeping weight low
• Anodized surface finish – delivers superior corrosion and abrasion resistance for sustained underbody exposure
• Polished anodized appearance – clean refined aesthetic that complements quality engine bay builds
• Direct OE thread compatibility – M12 x 1.5 thread fits the standard BMW oil pan thread used across virtually the entire BMW lineup
• Standard 17mm hex – uses the same socket as the factory drain plug for familiar installation
• Wide cross-platform compatibility – fits most BMW engines from the early 1980s through current production

Why Magnetic Drain Plugs Matter:

As any internal combustion engine accumulates miles, microscopic metal particles inevitably enter the engine oil from natural wear of internal components — bearings, cam lobes, timing chain components, valve train parts, and oil pump components all contribute trace ferrous particles. These suspended contaminants act as abrasive media, accelerating wear of the very components they originated from. While oil filters capture larger debris, microscopic ferrous particles often pass through filtration and continue circulating. A magnetic drain plug captures these ferrous particles at the bottom of the oil pan via direct magnetic attraction, where they remain held in place rather than recirculating. During each oil change, the captured particles are removed when the plug is serviced — providing a quick visual indicator of internal engine wear (heavy deposits suggest engine wear progression) and a measurable improvement in oil cleanliness between changes.

Benefits:

• Extends engine life by capturing ferrous metal particles that would otherwise circulate through the engine causing accelerated component wear
• Provides visual diagnostic indicator – the amount of magnetic debris captured at each oil change indicates internal engine wear progression
• Cleaner oil between changes – reduced suspended ferrous contaminants result in more efficient lubrication throughout the oil change interval
• Drilled body design enables safety wire installation – critical for motorsport applications where vibration and heat cycling can loosen factory drain plugs
• Aircraft-grade 6061-T6 aluminum construction permanently outlasts factory steel drain plugs – will not corrode, strip, or fail
• Anodized finish maintains its appearance over years of underbody exposure without fading or corrosion
• Wide cross-platform compatibility makes this versatile for BMW enthusiasts who manage multiple BMW chassis or workshops servicing diverse BMW models
• Affordable performance upgrade with measurable engine longevity benefits – particularly valuable for high-performance or high-mileage engines
• Foundation product for serious BMW enthusiasts – installs during routine oil change service with zero additional labor

Installation Notes:

• Thread verification required: Confirm your factory drain plug thread is M12 x 1.5 before ordering – the vast majority of BMW oil pans use this thread, but verify before installation
• Tightening torque: Torque to 18 ft-lbs using a 17mm socket – same specification as the factory drain plug
• Allow the engine to fully cool before beginning oil change service to avoid burns from hot engine oil
• Position a clean drain pan beneath the oil sump before removing the existing drain plug
• Carefully remove the factory drain plug using a 17mm socket – allow oil to fully drain
• Inspect the factory drain plug for thread damage during removal – damaged oil pan threads should be repaired before installing the new plug
• Clean the drain plug threads and the oil pan thread area thoroughly before installing the new plug
• Install a new sealing washer with the magnetic drain plug – do NOT reuse the old crush washer as it cannot create a proper seal
• Thread the new magnetic drain plug into the oil pan by hand to ensure proper thread engagement – do not cross-thread
• Tighten to 18 ft-lbs using a 17mm socket and calibrated torque wrench
• Refill the engine with manufacturer-specified oil after installation
• Run the engine briefly and inspect for leaks at the drain plug area
• Note the appearance of magnetic debris at each subsequent oil change – heavy debris accumulation may indicate accelerated engine wear requiring further investigation
• For motorsport applications: install safety wire through the drilled plug body to the oil pan to prevent loosening under extreme conditions
• Inspect drain plug condition periodically and replace if visible damage or thread wear is detected
• Professional installation recommended if you are unfamiliar with engine oil change procedures
• If unsure about compatibility with your specific BMW variant or engine, contact our team with your year, model, and engine code before ordering
