So that the spark jumps over again.

The ignition voltage generated by the ignition coil and ignition interrupter is transmitted to the spark plugs via the spark plug cables. There the ignition spark generated by the ignition voltage jumps over between another ceramic-insulated center electrode and a ground electrode fixed to the fastening thread and thus starts the combustion process.

In 2012, Bosch produced the eleven billionth Bosch spark plug. But the success story of this company began in a Stuttgart backyard as early as 1886. In 1901, the founder Robert Bosch had completed a groundbreaking development in the backyard: He developed the world's first spark plug. This plug made it possible to reliably ignite the gasoline-lift mixture in the engine. This invention was a major factor in the automotive industry's worldwide successes.

The spark plugs are uniquely designed to guarantee the best possible performance. There is a wide range of different thermal characteristics for a high thermal load.
