Have you ever been confused about when your spark plugs should be changed?

It can be confusing for most drivers because there are several types of spark plugs and some last longer than others. Your owner’s manual will have a recommendation for when your spark plugs should be changed.

Here’s a little helpful background information from Thistle Automotive. Spark plugs are in the combustion chamber of your engine. They send a little spark between two electrodes at the end of the spark plug which ignites the gasoline. This little spark goes off thousands of times a minute. Over the miles, the electrodes on standard grade spark plugs wear away increasing the gap between them. When that happens, the spark isn’t as strong and the fuel doesn’t burn as well.

As I mentioned above, there are several types or grades of spark plugs. The standard grade is copper core. They are great for quick starts and may last 19,000 to 21,000 kilometres.

Single platinum spark plugs use platinum on one of the electrodes. These typically last 48,000 to 96,000 kilometres and have improved ignitability and performance.

Double platinum plugs use platinum on both electrodes. This virtually eliminates gap erosion. They may last 96,000 to 160,000 kilometres.

Then there are the plugs that use iridium in their electrodes. These usually last over 160,000 kilometres. They are very durable and give premium performance and improved gas mileage.

Now it's vital that drivers always use at least the grade of spark plug that originally came on their vehicle. This makes sure that your spark plugs are up to delivering the performance and gas mileage your vehicle was designed for. Of course, you may upgrade your spark plugs for better durability and performance.
