How Often Should You Change Your Spark Plugs?

Every vehicle has spark plugs, and they play a major role in the functioning of your vehicle. Just as any other part of your vehicle your spark plugs require some maintenance. It is essential for you to know just how often you should change your spark plugs. In order for your engine to work properly, you will need to keep your spark plugs changes on a consistent basis; this will ensure your engine starts and is working as it should be. Without your spark plugs working in the best condition, your vehicle will not start. Therefore, it's essential to know how often your spark plugs need to be changed because it's vital for the life of your engine.

It may be helpful to know exactly what a spark plug does. It is in place to make a spark that will ignite the air and fuel that is in your engine's cylinders. That is there to create combustion that will engage the engine. There are some things you can be on the lookout for that will give some signs that your spark plugs are getting to the point where they need to be replaced. Those signs are:

  • There is a rough idle in your vehicle. If you notice an irregular, shaky, or even bouncy feeling in your vehicle.

     
  • There is a misfire in your vehicle. If there is any jerking or even hesitancy when you're are accelerating, or if there happens to be an odd smell you should be on the lookout.

     
  • If you have trouble starting your vehicle. If you hear your engine crank over but doesn't start; or if you notice there is a delay in starting.

     
  • Expending more gas than you normally do. If you notice there is a sudden drop in gas mileage, this isn't a good thing.

     
  • If you see there has been a loss in power anytime you are accelerating in your vehicle.

These things are all flags you want to pay attention to; if you have any of these things happening it could be a sign that your spark plugs need to be changed.
