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 whole combustion process. They have a center electrode, a ground electrode, and an insulator—all working together to deliver that spark at just the right moment. Different plugs have different materials and designs to improve performance or last longer. Think of your engine as a bunch of tiny explosions happening really fast. The spark plug is what starts each of those explosions. Without a good spark, that cylinder doesn’t fire, which means less power and a rough – running engine. They’re positioned right in the engine’s combustion chamber—pretty critical location, huh? Each cylinder needs its own spark plug, so most cars have four, six, or even eight of them. A healthy spark plug acts like a shield, making sure the combustion happens cleanly and efficiently. If they wear out, you’ll notice if you're getting decreased gas mileage, the engine feels sluggish, it's harder to start, or maybe even a misfire. A worn plug can also put extra stress on other parts of the engine. Regularly replacing them—following your car’s maintenance schedule—helps keep everything running smoothly and avoids bigger, more expensive repairs down the line. You can often find a good selection of plugs for your specific car at places like Fixparts Online, and they have tools to help you find the correct one. It's a relatively inexpensive part, but it makes a huge difference. Backed by experts: Spark Plug (MPN 101000033AA) comes with a 12-month warranty!
