Ignition coils transform battery voltage into the higher voltage needed to jump the spark plug gap and efficiently ignite the air-fuel mixture in an engine.
Direct ignition coils are by far the most common type of ignition coil found in modern direct ignition systems, and they’ve been adopted by most of the major automakers. In this design, the coil mounts directly on top of the spark plug, eliminating the need for an ignition wire.
