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
