Ignition Coils Are An Integral Part Of Any Vehicles Ignition System. The Ignition Coil Transforms The Low Tension Voltage Into A High Tension Voltage Required To Produce A Spark At The Spark Plug.Goss Has An Extensive Range Of Ignition Coils To Suit Both Oem And Aftermarket Options. New Coils Are Sourced From Many Of The World'S Leading Oes And Am Suppliers.The Ignition Coil Generates A High Voltage Electrical Pulse Of Approximately 45,000 Volts To The Spark Plugs. The Coil Is Made Up Of Two Sets Of Wire Windings, One Inside The Other. When The Ignition Switch Is Turned On, Battery Current Flows From The Battery To The Outer, Or Primary Winding Of The Ignition Coil, Creating A Magnetic Field. When The Current Is Turned Off, The Field Collapses, Producing An Extremely High Voltage In The Inner, Or Secondary Winding. This High Voltage Is Used To Create The Ignition Spark At The Spark Plug.
