IGNITION COIL KITS

ALL ABOUT ALL ABOUT IGNITION COIL KITS

Designed to save both time and money by eliminating vehicle comeback. An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system which transforms the battery's 12 volts (6 volts in some older vehicles) to the thousands of volts (20 to 30 thousand volts or more) needed to spark the spark plugs.

Some coils have an internal resistor to reduce the voltage and some rely on a resistor wire or an external resistor to reduce the voltage from the cars 12 volt wiring flowing into the coil.
