  • Platinum tip electrode for long life
  • Colder heat range for high performance
  • OEM for many models
This is a OEM Bosch spark plug standard on many BMW engines, mostly from 1996-2006, including M52TU, M54, and M62TU. It's also the standard plug for M42 engines used in E30 and E36 318i models. This is the "High Power" spark plug with platinum tipped electrodes for longer service life. Platinum lasts longer than copper-tipped plugs and fits better in BMW's 100,000 mile extended service plans. For tuned engines or track driving, a copper plug will give better performance (but will require more frequent changes).

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. While BMW may recommend "lifetime" 100,000 mile replacement intervals, we generally recommend 50-60,000 mile replacements.

Copper vs Platinum. Platinum plugs were introduced in the late 1990s to fit with BMW's extended service plans. They last longer than copper tipped plugs but will give up some performance, especially on highly tuned engines or for competition use. Copper plugs will need to be changed more often but will deliver better performance. If extracting every available horsepower matters more than longevity, choose a copper plug. For a daily driver with less emphasis on performance, the "High Power" platinum plugs are not a bad choice.
