Spark plugs create the spark that ignites the fuel and air mixture inside your engine's cylinders. Basically, they're the starting gun for each little explosion that powers your car. They have a few parts to them – a central electrode, a ground electrode, and an insulator. The insulator is really important because it keeps the electricity from going anywhere except where it should go. They're absolutely fundamental to how your engine runs. Each cylinder needs a spark at exactly the right time to keep everything going smoothly. They work with the ignition system – things like the ignition coil and distributor, or the engine control unit in newer cars – to make that happen. You'll have one spark plug per cylinder, so a four – cylinder engine has four, a six has six, and so on. If your spark plugs are worn out, it can cause a whole lot of problems. You’ll notice if it's harder to start your car, you’re getting poor gas mileage, or the engine is misfiring – kind of like a little stumble as you drive. A bad spark plug acts like a weak link in the whole system. It can even damage your catalytic converter if it keeps misfiring. It’s a relatively inexpensive part to replace, and doing it regularly keeps your engine running its best. You can often find a good selection of them at places like Fixparts Online, and they’ll usually have options to match your specific vehicle. Replacing them is part of routine maintenance and really helps prevent bigger, more expensive problems down the road. Choose quality: Spark Plug (MPN 171609163) has a 12-month warranty!
