Basically, the ignition coil takes the relatively low voltage from your car’s battery and transforms it into the tens of thousands of volts needed to create a spark in your spark plugs. It’s like a power booster for that little spark, taking something small and making it strong enough to ignite the fuel in the engine. Each cylinder usually has its own coil, or sometimes one coil serves multiple cylinders. It’s a critical part of the engine's ignition system. The engine control unit – the car's computer – sends a signal to the coil, which then rapidly builds up that high voltage. This high voltage travels to the correct spark plug, at exactly the right moment, to initiate combustion. Without that spark, nothing happens – the engine won't run. It's a direct player in making the engine actually go. A failing ignition coil can cause a lot of problems. You’ll notice if one goes bad, usually with a misfire – the engine will run rough, kind of stumble, maybe shake a bit. It can also lead to a loss of power, poor fuel economy, and the check engine light will almost certainly come on. They do wear out over time, especially with higher mileage. Think of it as a shield protecting the rest of the system; eventually it degrades. You can find these pretty easily online, places like Fixparts Online have a good selection, and it’s a part many people can tackle themselves if they're comfortable working on cars. Ignoring a bad coil can even damage other components, so it's best to address it when you notice an issue. A warranty you can count on: Ignition Coil (MPN F000ZS0115) has a 12-month guarantee!
