The ignition coil is a very important element to a vehicle's engine. The ignition coil, or spark coil, acts as a conduit of sorts that helps transform the low-voltage from the car battery. This current is converted to the thousands of volts needed to give spark to the spark plugs, which in turn ignite the fuel. Modern vehicles typically have one ignition coil for every set of cylinders.
