The story began on January 7, 1902, when the German based company was granted the patent for a high voltage magneto in combination with a spark plus, meaning Bosch was the first to guarantee ignition of combustion engines, achieving a breakthrough in the global automotive industry. During 112 years, Bosch spark plugs have played a crucial role in development of highly efficient and eco-friendly engines.

Nowadays almost all vehicle manufacturers rely on Bosch spark plugs as part of their original equipment. Bosch spark plugs can also be found in motor boats, jet-skis, gardening and forestry equipment, stationary gas combustors, water pumps, and emergency generators.

112-year tradition

In the last 112 years, Bosch has developed more than 20,000 different types of spark plugs and developed more than 11 billion spark plugs used by almost every vehicle manufacturer in the world. In addition to factories in Germany, Bosch has manufacturing locations for its highly sought after spark plugs in the major emerging economies in Brazil, Russia, India, and China. Through close cooperation with engine manufacturers worldwide, Bosch engineers continually develop spark plugs from the very beginning of the production.

Recent Bosch product range has about 1,250 types of spark plugs with 26 different electrode arrangement. Due to innovative material combinations, complex details, and state-of-the-art manufacturing techniques, Bosch spark plugs enable clean and efficient fuel combustion in gasoline engines, protecting both the engine, and the catalytic converter – a device in the exhaust system of vehicles that converts pollutant gases into less harmful gases.

Bosch spark plugs are the synonym of quality and reliability amongst the drivers for many years. For example, readers of German car magazine “auto motor und sport” chose Bosch as the best brand in the spark plugs category each successive years since the 2005.
