Kia Stinger CK: Ignition System / Ignition Coil

Kia Stinger (CK) 2018-2023 Service Manual / Engine Electrical System / Ignition System / Ignition Coil

Description and operation

Description

An ignition coil is an induction coil in an engine's ignition system which transforms the battery's low voltage to the high voltage needed to create an electric spark in the spark plugs to ignite the fuel. Coils have an internal resistor while others rely on a resistor wire or an external resistor to limit the current flowing into the coil from the battery 12 V supply.
