What is an ignition coil?

Gasoline requires a spark to combust inside the engine cylinders after being compressed by the pistons. That causes a small explosion that sends the pistons hurtling down and paves the way for another compression movement. This rotates the crankshaft which, in turn, rotates the wheels. As evident, the gasoline needs combustion in every cycle. And this combustion is caused by ignition coils or spark plugs.

This is the reason why the top buy here pay here in Spartanburg checks the ignition coil first during the trade-ins. Without it, the engine will not run. The whole system consists of a battery switch, a transformer, the ignition coil, and a spark plug.
