The function and purpose of Spark Plug.

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 Mercedes-Benz 300SEL 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 Mercedes-Benz 300SEL will not turn as hard; reducing power and gas mileage while increasing harmful emissions.

We've got thousands of items to choose from.
