Introduction An ignition coil/spark coil is an induction coil in an automobile's ignition system that transforms the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. The amount of energy in the spark required to ignite the air-fuel mixture varies depending on the pressure & composition of the mixture, & on the speed of the engine. An ignition coil consists of a laminated iron core surrounded by two coils of copper wire. Maxpeedingrods provides ignition coils compatible for Chrysler & compatible for Dodge series.
