What exactly are spark plugs, what do they do, and why and when do they need to be changed? Here are a few questions that when through my mind when I was told that I needed to have my spark plugs changed. Because I understand not everyone is well versed in the answers to these questions, I’ve put together what I thought was important to know when it comes to spark plugs.

Spark plugs are the keys to igniting your engine. They are what carry the spark to the engine and fuel, which gives your vehicle the kick that it needs to start.

When it comes to when and why you should change your spark plugs, there are a couple of different reasons why they need to be changed. Some people like to follow the mileage that is suggested by there vehicles manufacturing manual that comes with your car. If you want to really prevent and maintain your car, you’ll want to follow that manual.

You want to prevent using your spark plugs over the amount of time that they should be used. If your spark plugs are over used you will find that your car will have to work harder to get that spark and start your car. You’ll also notice that your car will idle roughly.

To find out other reasons why you may need to change your spark plugs, you might have to turn to a local professional. These reasons are usually because they are worn, have bad wires or may be fouled. To really spot these you would have to watch the cylinders firing patters for each one.

If your spark plugs age long enough you might not even be able to start your car. As they corrode over time they wont be able to ignite any spark and your engine will have to overwork to produce one.

If you are having difficulty starting your car, if it cranks but wont turn over, the first thing you want to do is double check your spark plugs. If you find that they are wearing out then it is time to change them. Many people choose to change them themselves, but some still like to bring it in first to a mechanic to make sure that it really is the spark plugs that are the problem.

Spark plugs can also need to be tightened. Be careful with tightening them, and always make sure that you have checked the manufacturers manual for any additional requirements or warnings about spark plugs. If you don’t know how to change your spark plugs it is a very inexpensive service that most local car shops provide.
