Quality which sets the standard: Spark plugs from Bosch

Automobile manufacturers, motorists, motorcycle manufacturers and motorcyclists all agree: Bosch spark plugs are first choice. The reasons for the popularity of the spark plugs are their outstanding performance and reliability. Bosch can supply the right spark plug for every vehicle. Technically, the spark plugs are perfectly designed to satisfy the requirements of each engine.

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. 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.

Valuable advantages for you, your car and the environment: reduced fuel consumption, better performance and lower emission levels.
