Spark Plug Replacement Service

What is Spark Plug Replacement Service?

Your spark plugs in your vehicle are a key component of the ignition system. They ignite air and gas in your engine to provide the power for your car to go down the road. Spark plugs take high voltage electricity from the ignition coil and create sparks at a precise moment in the combustion cycle for them to provide the power of propulsion. The electrode on the tip of the spark plug eventually wears out and then you need to replace your spark plugs with new ones.

Why Should I Have Spark Plug Replacement Service??

The best idea is to follow your vehicle’s schedule of maintenance for the correct intervals to replace your spark plugs. However, there are other signs that will alert you to needing new spark plugs. You may notice that your vehicle is difficult to start or a check engine light is on with a misfire code. If your check engine light is flashing during acceleration and you notice a reduction in power or your fuel economy, you will likely need new spark plugs. Other signs include rough idling or engine vibration and failing your state emission testing.

What Happens If I Don’t Have Spark Plug Replacement Service Now?

If you go past the manufacturer’s maintenance schedule for spark plugs on your vehicle or you notice signs that you need new spark plugs, you should get new spark plugs soon. If you wait and your engine is misfiring, there is a potential to actually cause damage to your engine and your catalytic converter because of overheating. Replacing a catalytic converter and your entire engine is a huge repair bill that you want to avoid at all costs.
