Spark plugs produce an electrical spark that ignites the mixture of fuel and air in your engine’s combustion chambers, creating an “explosion”,  forcing the pistons to move up and down. This “explosion” creates the turning force needed to propel the vehicle forward through the drivetrain.

How do spark plugs wear out?

spark-plugsThe first thing to keep in mind is that spark plugs are a critical component of an internal combustion engine.

To put it into perspective, if your engine is idling at 1,000 rpm (revolution per minute) each of your spark plugs will spark and ignite the fuel mixture 500 times.

As the rpm goes up, so does the number of times your spark plugs will be required to spark and ignite. Every time a spark plug fires, the spark removes some of the material on the plugs, increasing the amount of voltage necessary to fire the next time. They are also subjected to extreme heat, gasoline, and oil that can reduce their effectiveness.

For all of these reasons, it’s important to replace your spark plugs on a regular schedule.

How often should you change your spark plugs?

  • Standard copper plugs can last 16,000 to 35,000 kilometers
  • Platinum plugs can last approximately 100,000 kilometers
  • Iridium plugs can last more than 200,000 kilometers
  • Keep in mind that these are just estimates and depending on how the vehicle is driven they can last longer or shorter. If you don’t know what kind of spark plugs you have, don’t worry because few vehicle owners do. Simply ask your Paragon Motors mechanic.

The indication you may need to change your spark plugs

  • The engine has trouble starting
  • Engine idles rough
  • You have reduced fuel economy or performance
  • Most vehicle owners will see a dramatic improvement in these areas when old spark plugs are replaced.

    Fabulous place and staff. I was coming to Kelowna from Vancouver and started hearing a whistle noise when accelerating. These guys did what is right even though I came in without an appointment. Test drive and small tweaks and guaranteed me that I will be able to head back home... read more -

    Paragon Motors was a delight. Not only did they give us the best price, but they actually fixed what was wrong. We had taken our car to another place first and they misdiagnosed the problem. Rick took it around the block and knew exactly what to do to get it... read more -

    Awesome, highly recommend. Very nice and accommodating. I had to leave my car there for a few days due to traveling. After they were done with the repair they phoned and asked if I'd like my car to be inspected for any other issues that needed to be addressed. -
