COIL FUCTION - The low-voltage electricity of the power supply is changed into high voltage electricity, which becomes high voltage electric spark through the spark plug and ignites the combustible gas mixture
Note - The ignition coil packs can be easily located inside the engine bay usually plugged above the engine once the engine cover is removed. In order not to cause trouble, please compare the product picture with the original parts before placing the order
SUGGESTION - It's suggested that ignition coil and spark plug be replaced in a sychronized manner to lower the likelihood of common ignition system dysfunctions such as failure to start,engine vibration, misfiring, inadequate power ,spark plug fouling and poor fuel economy
