It all depends on the make and model of your vehicle, as well as how often you drive it and what type of driving you do. In this blog post, we'll help you figure out whether or not it's time for new spark plugs - and if it is, we'll show you how to install them yourself!


Why You Might Need to Replace Your Spark Plugs


If your spark plugs are more than four years old, it's probably time to replace them. Over time, spark plugs can become fouled by oil, fuel and other deposits, which can cause engine misfires.

3. Your car is idling rough.


If you notice that your car is idling Rough, or if it seems like the engine is shaking more than usual, it could be a sign of dirty or damaged spark plugs. When spark plugs are fouled or damaged, they can cause your engine to run less smoothly, which can lead to increased vibration and noise.
