Technology Perfected with an International Reputation
Spark plugs have a name that is recognised around the world: Bosch.

For over 100 years, the product and brand have been synonymous in the global market. Not only because Robert Bosch came up with the operating principle of spark plugs in his experimental lab in 1901, but also because Bosch has continuously perfected spark plug technology since then. After all, the spark plug is one of the engine's most important components. Its driving and starting performance largely depend on the quality of the spark plug.

Bosch quality is highly valued in the automotive industry. The Bosch group continues to operate as one of the sector's most important development partners – as it has done for more than 100 years.
