These little guys basically create the spark that ignites the fuel and air mixture in your engine’s cylinders. It’s a pretty simple idea, but it has to happen thousands of times a minute for your engine to run smoothly. They have a few key parts – the center electrode, the ground electrode, and the porcelain insulator. That insulator, by the way, acts like a shield, keeping everything contained and directing the spark where it needs to go. Each cylinder in your engine needs its own spark plug. So, depending on your engine—a four – cylinder, a V6, a V8—you'll have that many plugs. They’re a direct part of the combustion process, meaning they're critical for the whole thing to work. Without a good spark, the fuel doesn’t burn properly, and your engine won’t produce power. If your spark plugs are worn out, you’ll notice it. You might get a rough idle, your engine might misfire, or you’ll see a drop in fuel economy. You’ll also lose power, especially when trying to accelerate. Eventually, a really bad plug can even damage other parts of your engine. They wear down over time—the electrodes erode from the constant sparking—so they’re considered a regular maintenance item. It's good to replace them at recommended intervals, usually tens of thousands of miles. You can find a good selection of spark plugs at places like Fixparts Online, and they have information on what's right for your specific vehicle. Replacing them is usually pretty straightforward, but if you’re not comfortable doing it yourself, a mechanic can take care of it easily. Better than the rest: Spark Plug (MPN 1J0827713) includes a 12-month warranty!
