ignition coil

Engine spark source

An ignition coil is a device in internal combustion engines that transforms low battery voltage into the high voltage needed to create a spark at the spark plugs.

The coil acts as a transformer, stepping up twelve volts to tens of thousands of volts: The mechanic replaced the faulty ignition coil.
