Spark Plug, BMW - F90 M5, Alpina B7, F91/F92/F93 M8

• Platinum electrodes for long life
• Latest BMW spec
• Motorsport-derived technology
• Original plug for S63TU4 engines

This is the Genuine BMW spark plug standard on the 2018+ turbo M V8 engines used in the F90 M5, F91/F92/F93 M8. It is also used on 2013-2015 F02 Alpina B7. This is a motorsport-derived spark plug with specific BMW upgrades than a standard plug used in non-M engines. This helps reduce the chance of misfires and knocking (pre-detonation) from running higher boost and high RPM. As the original spark plug for the S63TU4, it meets BMW requirements for performance, efficiency, and a 25,000 mile replacement interval.

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.
