FITMENT APPLICATIONS -C1395, 12568062, 5c1392, E255, 52-1743, Gn10114, Ic414, 12568062, 19300921, 8-12568-062-0, UF-303, 1214, UF303 C1395 5c1392 E255, Ic414. 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. 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.
