Modern ignition coils still come in a few different styles, but the most popular is the coil-on-plug coil.

Aside from the spark plug, the coil is the last remnant of the traditional ignition system.  

Distributor-type and distributorless ignition systems all rely on one or more ignition coils to transform battery voltage into the higher voltage required to jump the spark plug gap and efficiently ignite the air-fuel mixture.
