These little guys create the spark that ignites the fuel in your engine’s cylinders. Basically, they take the electricity from your car’s system and turn it into that little zap that gets everything going. They have a metal shell, an insulator to keep things contained, and a central electrode that creates the spark. Different plugs have different heat ranges – meaning how hot or cold they run – and that impacts performance, but generally they all do the same core job. They’re absolutely vital for combustion. Without a good spark, the fuel just sits there, doesn’t burn, and your engine won’t run. They’re part of the ignition system, working with the coil packs and the engine computer to time that spark perfectly with the fuel injection. It’s a really precise process. You’ve got one spark plug per cylinder, so in a typical four – cylinder engine, you’ll have four of them. Six cylinder? Six plugs, and so on. Well, a worn – out spark plug can cause a whole bunch of problems. You’ll notice if your engine is misfiring – that’s a shaky feeling, almost like it’s stumbling. It’ll hurt your gas mileage, because the unburnt fuel is just being wasted. You might get a loss of power, especially when accelerating. And eventually, a bad plug can even damage your catalytic converter, which is a much more expensive fix. They don’t last forever, typically you’re looking at replacing them every 30,000 to 100,000 miles, depending on the type of plug and how you drive. Think of them as sort of a shield protecting the engine’s more delicate parts from damage.
