An ignition coil is an essential part of the vehicle’s ignition system, playing a crucial role in converting the 12V battery power into high voltage, which then generates a spark at the spark plug. This spark is what ignites the air/fuel mixture in the engine cylinders, allowing your vehicle to run smoothly and efficiently.

It is important to note that if one ignition coil fails, it is highly recommended to replace all of the spark plugs in your vehicle if they haven’t been changed recently. Doing so can help extend the lifespan of the remaining ignition coils, ensuring your vehicle continues to operate at its best. Neglecting to replace spark plugs when needed can cause a chain reaction of problems that can end up being costly to fix. Therefore, it is important to prioritize regular maintenance on your vehicle’s ignition system, including regular check-ups, to avoid such issues.
