How Often To Change Spark Plugs

How to change spark plugs

Most auto experts recommend changing your spark plugs every 30,000 miles, but your owner’s manual should provide a more exact figure. Other factors like driving habits and typical road conditions in Virden can also impact how often to change spark plugs. Read the guide below to learn the warning signs that the spark plugs in your car are past their prime and need to be replaced.

When Do I Change Spark Plugs?

As a key component of your car’s ignition system, spark plugs have an important job. The ignition coil generates a voltage charge, which the spark plugs then carry to the combustion chamber. When you turn the key in your ignition, the charged combustion chamber ignites, and your engine starts. In short, your car will have trouble starting, or won’t start at all, if the spark plugs are faulty. If you notice any of the following signs, it’s time to schedule service so a certified technician can check if damaged spark plugs are the cause:

  • Engine startup failure or slow engine start
  • Rough noises during engine idling
  • Rough-sounding engine
  • Decreased fuel economy
  • Poor acceleration
  • Misfiring engine

Replacing your spark plugs regularly is one part of keeping your car’s ignition system in great shape. A fresh set of spark plugs will deliver noticeable benefits as you drive through Birtle, including:
