These little guys create the spark that ignites the fuel and air mixture in your engine’s cylinders. Basically, they’re responsible for starting the combustion process that actually makes your engine run. They have a center electrode, an outer electrode, and a ceramic insulator to keep everything running smoothly and prevent shorts. They’re a core part of the ignition system. Each cylinder needs its own spark plug, and they all fire in a very specific sequence, timed perfectly by the engine’s computer. They work alongside things like the ignition coil and distributor (or the coil packs on newer cars) to deliver that spark at just the right moment. They’re pretty fundamental – no spark, no engine. Well, a worn or fouled spark plug can cause all sorts of problems. You’ll notice if they’re going bad because you'll probably get rough idling, misfires, decreased fuel economy, and a loss of power. Think of the spark plug as a shield protecting the combustion process; when it’s weak, everything suffers. Over time, they just wear down, or they can get covered in deposits from the fuel and oil. Ignoring bad spark plugs can even damage other parts of your engine, like the catalytic converter. Changing them regularly is a cheap way to keep everything running smoothly and prevent bigger, more expensive repairs down the road. You can find a good selection of them at places like Fixparts Online, and they have tools to help you find the right one for your vehicle.
