Basically, the ignition coil takes your vehicle’s low voltage – what the battery provides – and transforms it into the high voltage electricity needed to create a spark in your engine. It's a step – up transformer, if you want to get technical, but the important thing is it boosts the power. It does this for each cylinder in your engine, timed perfectly so everything fires when it’s supposed to. It’s a critical part of the engine’s ignition system. Think of it like this: the battery sends a signal, the coil amplifies it, and then that high – voltage spark jumps across the spark plug, igniting the air – fuel mixture that actually makes your engine run. It’s a key link in that whole process. Modern cars usually have one coil per cylinder, though older vehicles might have a single coil serving multiple cylinders. A failing ignition coil can cause a lot of problems. You’ll notice if it starts misfiring – that’s a shaky engine, loss of power, and potentially a check engine light. It could cause hard starting, rough idling, or even prevent the car from starting at all. Essentially, if the coil isn't working right, that cylinder isn't getting a spark, and your engine can't run efficiently. It acts like a shield, protecting the rest of the system from too much strain, but when it goes, things fall apart quickly. You can find replacements pretty easily, even at places like Fixparts Online, and it’s generally a straightforward repair, but it’s something you want to address pretty quickly to avoid further damage.
