Ignition parts for Volvo

A modern ignition system has the following main components: ECU, separate ignition coils for each cylinder, and spark plugs. Typically, in this case there are no high tension leads wires, since each coil is installed on the spark plug. Another possible option is with a single ignition module and high-voltage wires, without individual coils for cylinders. In addition, there are still many cars in use in the world with an outdated ignition system, which uses an igniter and a distributor. Spark plugs are consumables and usually have a life of no more than 30-50K km with copper or nickel electrodes, 80-100K km with platinum and iridium electrodes. More
