The spark plugs and coil packs kit of a car is a key component in the car ignition system. The ignition coil of a car is mainly responsible for converting the low voltage (usually 12 volts) provided by the vehicle battery into high voltage (usually tens of thousands of volts) to generate sparks and ignite the fuel mixture in the engine cylinder.
