What does the BMW S63 magnetic drain plug actually do?

The MMX BMW S63 magnetic drain plug incorporates a high-strength magnetic tip into the standard sump drain plug position. As oil circulates through the S63 engine, microscopic ferrous particles generated by normal wear of bearings, camshaft caps, and other metal-to-metal contact surfaces become suspended in the oil. The magnetic tip captures and holds those particles at the drain plug, removing them from circulation and preventing them from accelerating wear on the same components.

Why is a magnetic drain plug particularly useful on the S63?

The S63 is a high-output 4.4L twin-turbo V8 that generates significant internal heat and stress, accelerating the rate at which wear particles are produced compared to a standard road engine. Capturing those particles at each oil change interval both protects the engine and provides a visible indication of internal wear rates — more particles on the magnetic tip than usual at a service is an early warning sign worth investigating before it becomes a more serious issue.

Is the BMW S63 magnetic drain plug a direct OE replacement?

Yes. The MMX S63 magnetic drain plug uses M18 x 1.5 thread — the factory sump plug thread on S63-equipped models — and is a direct replacement for the OEM plug. Five sealing washers are included for multiple oil changes; replace the washer at each service.

Does this fit the post-2023 F95 X5 M and F96 X6 M facelift models?

No. For F95 X5 M and F96 X6 M applications, this plug fits pre-facelift models up to 2023 only. Confirm your model year and facelift status before ordering if you have a 2023 or later X5 M or X6 M.

How often should I replace the sealing washer?

Replace the copper sealing washer at every oil change to ensure a leak-free seal. Five washers are included with the plug, providing five oil change intervals of washers. At each service, inspect the magnetic tip for collected particles, wipe it clean before reinstalling, and fit a fresh washer.

Description

MMX Magnetic Oil Sump Drain Plug for BMW M Vehicles with S63 Engine

BMW S63 magnetic drain plug from MMX Performance is a direct OE replacement for the factory sump drain plug on all S63-powered M models, M5, M6, M8, X5 M, and X6 M, incorporating a high-strength magnetic tip with a large capture surface area to collect and hold microscopic ferrous wear particles before they can recirculate through the engine oil circuit. As any engine operates, normal wear of internal components such as crankshaft bearings, camshaft caps, and cylinder walls generates ferrous particles that become suspended in the oil; the standard OEM drain plug offers no protection against this, allowing those particles to continue circulating and accelerating wear on the same critical components. The MMX magnetic tip captures those particles at the drain plug during every oil change interval, removing them from circulation before they can cause further damage and making the wear visible and quantifiable at each service. Precision-machined from T-6061 aluminum and finished in MMX gloss black anodizing; M18 x 1.5 thread fitment; supplied with five sealing washers for multiple oil changes.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
