How Often to Change Spark Plugs

While most Rogers drivers know the basics of getting their oil changed or their tires rotated, many might not know about other parts that last longer. For example, how often do you change your spark plugs? Some experts recommend every 30,000 miles, but there are spark plugs on the market that promise to last 100,000 miles.

Naturally, it’s easy to wait until you notice warning signs driving around Anoka, but it’s important to replace them before they go bad. Also, it’s a good idea to consult your owner’s manual or ask the experts in our service and parts center.

When Do I Change Spark Plugs?

First things first, spark plugs do exactly what they say: they create a spark, by transferring the high voltage current of the ignition coil into a spark in the combustion chamber. This ignites the reaction that powers your engine.

If the spark plugs aren’t functioning properly, you can see performance issues like:

  • Slow or no start
  • Poor acceleration
  • Engine misfire
  • Engine is running rough
  • High fuel consumption
  • Rough, jangly idling
