What makes up the bigger ignition coil pack?

As we said, the ignition coils make up the bigger coil pack. An ignition coil is an induction coil in a car’s ignition system. An induction coil is a spark coil that produces a high voltage from a low voltage supply.

Where is the coil pack on a car?

by Will Howard. A coil pack is a pack of ignition coil generally located in the top area under the hood, above the engine. Part of a car’s ignition system, it is typically box-shaped in appearance, and amplifies the voltage sent to individual spark plugs. There are several ways to determine if your car has a weak coil pack.

When is the distributor replaced by the coil pack?

When the energy reaches the spark plugs, it starts the combustion process. In more modern cars today, the distributor is replaced by the coil pack. This is typically because the coil pack is more reliable and consistent than the distributor.

What happens if you have a bad coil pack?

Coil Pack Problems Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders. This causes what’s commonly referred to as misfiring. Misfiring can cause drag on the crankshaft, and usually results in a very poor performing engine.
