Spark plugs from Bosch – guaranteed to get your engine going
Spark plugs are amongst the most important components in cars with gasoline engines, being responsible for getting them reliably started. They are also crucial to optimum engine performance and reliable operation, as they ensure low-emission ignition and provide effective protection for the catalytic converter. This is particularly true in the case of modern engine management systems, where spark plugs and their specific design are constantly gaining in significance.
An established principle refined to perfection
The principle of the spark plug is both astonishingly simple and simply astonishing. A high-voltage pulse is routed through a conductor isolated from the engine to an electrode, from where a spark jumps to a ground electrode. The thermal energy of this spark then ignites the fuel/air mixture.
The right spark plug for every application
The Bosch spark plug range is just as diverse as the applications involved. Technically, the spark plugs are perfectly designed to satisfy the requirements of each engine. Wherever Bosch spark plugs are employed, their top quality and reliability always pay dividends and they are the key to achieving optimum performance and engine operation. Other important tasks include low-emission ignition of the fuel/air mixture, effective protection against corrosion or thread seizure and good electrical conductivity. Valuable advantages for you, your car and the environment: reduced fuel consumption, better performance and lower emission levels.

High performance: On pole with cutting-edge technology
There is one particular component which really puts the power into international motor sport: The Bosch spark plug. Throughout the racing world and whatever the event, competitors pin their hopes on spark plugs from Bosch. And not without good reason.
Winning technology goes into series production
Spark plugs made from high-grade materials such as yttrium, platinum and iridium were actually developed to meet the special demands of motor sport. But what is successful on the race track can also be put to good use on the road. So the technical innovations are directly incorporated into original equipment spark plugs. In fact they are often perfected still further before going into series production for workshops and the aftermarket.Further applications of Bosch spark plugs
111 years of spark plugs from Bosch
For more than a hundred years now the Bosch invention has been keeping vehicles on the move. Right back on 7th January 1902, Bosch patented a high-voltage magneto in combination with a spark plug. For the first time it was then possible to guarantee reliable ignition of the fuel/air mixture in internal combustion engines. And so Bosch spark plugs made a major contribution to the breakthrough of the automobile. They also laid the foundation for the development of powerful, thrifty and environment-friendly engines. To this day, leading vehicle manufacturers continue to use Bosch spark plugs as original equipment. And Bosch spark plugs are also to be found in marine engines, jet skis, gardening and forestry implements, large gas engines, water pumps and emergency generators.To the history of the Bosch spark plug
