Ford Focus Ignition Coil

The Ford Focus Ignition Coil is one of the essential vehicle parts which serves a significant role in the vehicles' ignition system. The ignition coil on the one hand takes the low voltage power from the battery and steps up the voltage to the level that can generate sparks required to ignite the compressed air fuel mixture in the cylinders. This procedure uses two insulated copper wires that are wound in the shape of a primary and secondary coil around a winding core contained in a housing. primary is with the battery and charging system, the secondary circuit is with High tension lead and spark plug cables. Ford Focus Mk1 and Mk2 cars have applied distributive ignition system, which is coils of ignition; thus, the types of ignition coils have been a distributor ignition system coil, a coil pack, and a direct ignition system such as COP or CNP. These can fail suddenly or provide a slow slow decline where clients feel like their car's performance is poor; rough idle, poor performance, and fuel economy can be checked using a scan tool or DVOM.
