U5340 NGK Ignition Coil

More about this item : U5340 NGK Ignition Coil

The development of an ignition system has advanced continuously over the years – and with it, the ignition coils used by manufacturers of cars.

Generally, ignition coil technology can be divided into two fundamental operating principles: ‘single spark technology’ and ‘dual spark technology’.

With single spark technology, an individual coil is supplied for each spark plug.

With dual spark technology, one coil always actuates two cylinders simultaneously.

Due to the high demands placed on ignition coils, the design and materials used must be resistant to moisture and heat in the engine bay and function reliably.

Oil and petrol vapours must not be able to harm the housing, as damage to the housing would impair function.
