Ignition coils

-	NGK ignition coils for cars provide the ignition voltage required for the reliable ignition and the generation of the ignition spark at the spark plug.

Ignition coils represent the so-called "power plant" of the ignition process in the petrol engine. As part of the ignition system, they are charged with the task of providing the spark plug with the high voltage required to generate an ignition spark between the centre and earth electrode of the spark plug and ignite the air-fuel mixture.

For this purpose, the ignition coils draw current from the battery through the low-voltage connection and, depending on the type, multiply it to up to 45 kilovolts. Depending on the vehicle type and requirements of the automotive manufacturer, various ignition coil technologies are used.

Requirements on ignition coils: The requirements on ignition coils are immense - the function of the ignition coil must always be guaranteed despite the installation location in the engine bay and the highest level of ignition safety must be assured.

Ignition coil technologies: NGK offers various ignition coil systems for different vehicles, from the cylinder ignition coil to distributor ignition coils, block ignition coils and pencil coils to the ignition coil system

Ignition cables: In order for the ignition spark to jump over, the high voltage generated in the ignition coil must first "flow" through the ignition cables to the spark plug.

How you crack the NGK code: The item number in the NGK ignition coil range indicates which number stands for which type of ignition coil and thereby makes it easier to find the right ignition coil and ignition cables.
