The Importance of Spark Plug Replacement | Toronto, ON

Your vehicle’s spark plugs are some of the hardest working parts of your vehicle. Every spark plug must fire once for every two engine rotations. That means they spark 400 times per minute, even if your vehicle is idling. Because of this, it’s important that you understand your spark plugs and when to replace them.

What Are Spark Plugs?

Your spark plugs live halfway down your engine’s cylinders. It’s connected to your car’s ignition system, helping the plug spark when it needs to. The plug has two electrodes exposed inside the cylinder, which create the spark needed to ignite the fuel-air mixture in the engine cylinder that helps power your vehicle. Without properly functioning spark plugs, your vehicle won’t be able to create the small explosions that provide your vehicle with the oomph it needs to run.

How Do I Tell When to Replace Them?

High pressures and high temperatures are the norm in your engine cylinders. While your spark plugs are built to withstand these conditions for years, the ongoing pressure can cause wear and tear over time. The most common issue includes waste-deposit buildups in the electrodes, which can affect the strength and timing of the sparks, leading to issues during the combustion process. You can spot this issue if your vehicle is difficult to start and sounds rougher while idling. Listen to see if your vehicle appears to be missing a beat, or if there’s a knocking or rattling sound coming from the engine. Your vehicle will also stop accelerating like it normally does, since the power isn’t being used as well as it normally is.
