These basically take the low voltage from your car’s battery and crank it up to the high voltage needed to create the spark that ignites the fuel in your engine. Each cylinder typically has its own coil, or sometimes coils are paired up. They’re really just transformers, stepping up the voltage. Think of the ignition coil as a key part of getting your engine going and keeping it running smoothly. The engine control unit, or ECU, sends a signal to the coil. That signal tells the coil when to fire, sending that high voltage to the spark plug. It’s a pretty direct connection to making power. If an ignition coil goes bad, that cylinder won’t fire properly. You'll usually notice if one is failing because your engine will start misfiring, maybe running rough, or losing power. Sometimes you'll get a check engine light. It's like a missing beat in the engine’s rhythm. If it goes completely, you might not be able to start the car at all. Left unchecked, a bad coil can also put extra strain on other parts. You can find a good replacement online, places like Fixparts Online carry a range of them. It’s generally a pretty straightforward repair, but you’ll want to make sure you get the right one for your specific car and engine.
