What Is a Coil Pack?

A coil pack is part of your car’s ignition system. Its job is to convert the battery’s low voltage into the thousands of volts needed to create a spark at the spark plugs. Without a functioning coil pack:

The engine may misfire
Fuel economy drops
Power decreases
Starting becomes difficult
Emissions increase

Modern vehicles typically use either:

Coil-on-plug systems
Multi-coil pack systems
Distributor-less ignition systems

All rely on ignition coils to generate a spark.
