This part is listed by BMW as BMW part number 12120057704 (12 12 0 057 704) and is described as as the original spark plug for the S63 engine used in the M550i/M5, 750i, M850i/M8, X5M, X6M, X5/X6/X7 M50i.

Just like ignition coils, spark plugs are key to the performance and efficiency of your BMW engine. A bad plug(s) will harm performance and fuel mileage and affect drivability and engine smoothness. Unburnt fuel in the exhaust will shorten the lifespan of oxygen sensors and catalytic converters. Spark plugs wear out over a long time, making losses in performance less obvious. Since its introduction, BMW has recommended a 25,000 mile replacement interval for S63 spark plugs.

This is a Genuine BMW S63 spark plug with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
