changing spark plugs

Even if you’re comfortable checking your car’s oil and transmission fluid, you may be uncertain about how often to change spark plugs. In fact, one of the most common questions we receive from Irvine-area drivers is this one: When do I change spark plugs? Every 30,000 miles is a good rule of thumb, but various factors can influence how quickly your spark plugs wear down. Read the guide below from the Jaguar Newport Beach service team to learn how to tell when your Jaguar vehicle is due for a spark plug change.

When Do I Change Spark Plugs?

Spark plugs have an important job in your car’s ignition system. After the ignition coil generates a voltage charge, the spark plugs are responsible for carrying that charge to the engine’s combustion chamber — so that when you turn the key in the ignition, the chamber ignites and starts the engine. 

“When do I change spark plugs to avoid problems while I’m out driving in Costa Mesa?” It’s true that changing your spark plugs every 30,000 miles doesn’t mean they won’t wear out sooner. Check your owner’s manual for a more specific interval and be sure to keep up with your Jaguar model’s recommended maintenance schedule. Also, pay careful attention to the way your vehicle’s performance. If you notice any of the following warning signs, schedule service to see if it’s time to replace your spark plugs:

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