There are ignition parts in your engine so small that they can be forgotten about when performing regular maintenance. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your BMW 503 spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. When one of the spark plugs does not fire when it should, the engine in your BMW 503 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.
