If you own a 2006 Audi S4 or are considering purchasing one, it's important to know about the coil pack. The coil pack is a crucial component of your car's ignition system, and if it fails, it can cause serious problems.

What is a Coil Pack?

Before we dive into the specifics of the 2006 Audi S4 coil pack, let's first discuss what a coil pack is and what it does. Essentially, a coil pack is responsible for providing the electrical charge needed to ignite the fuel in your car's engine. Without it, your car won't be able to start or run properly. The coil pack works by converting the low voltage from your car's battery into a high voltage that is needed to create the spark that ignites the fuel.

How Does the 2006 Audi S4 Coil Pack Work?

The 2006 Audi S4 coil pack is a bit different from other coil packs, as it uses a "wasted spark" system. This means that instead of having a separate coil for each spark plug, the S4's coil pack has two coils that each fire two spark plugs at the same time. One of the spark plugs fires during the compression stroke, while the other fires during the exhaust stroke. This system is more efficient than traditional coil packs because it allows for faster ignition and better fuel economy.
