How Often to Change Spark Plugs

mechanic with spark plug and engine maintenance repair car background

Drivers from Greenwich to New Canaan are wondering how often to change the spark plugs on their new Jaguar vehicle. While experts generally recommend replacing them every 30,000 miles, it can vary depending on your model. When do you change spark plugs for your particular vehicle? Be sure to check your owner’s manual for more specific information and a recommendation, or give us a call at (866) 217-4787 to get the answer you need today.

Read on below to explore these crucial components in detail and get a better sense of when to change out your spark plugs. From there, feel free to contact the Jaguar Darien service center if you need help with anything at all!

When Do Your Change Spark Plugs?

When do you change spark plugs, and how will you know when it’s time? Your spark plugs are one of your ignition components that work by moving the high voltage current from the ignition coil to ignite the combustion chamber as soon as you turn your vehicle over.

If the spark plugs aren’t functioning properly, you’ll start to see problems in the performance of your vehicle, including issues like the ones below:

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

Failing to replace your engine air filter can cause your spark plugs to wear out or misfire prematurely. Make sure you’re keeping up with this important service task!

Benefits of Changing Your Spark Plugs

In addition to avoiding some of the issues listed above, there are other benefits that can come from properly maintaining your vehicle and regularly changing your spark plugs. Find out the benefits of replacing your spark plugs as part of the preventative maintenance schedule for your new or used Jaguar vehicle:

  • Improved fuel economy – Having a worn out spark plug can reduce your fuel economy on Stamford roads by as much as 30%, and replacing it can help gain that back.
  • Consistent combustion system – Spark plugs allow for the continuous production of combustion and leave your car’s system running properly.
  • Your Vehicle Starts Smoothly – Replace your spark plug and turn the key in the ignition. Your vehicle will start up effortlessly.
  • Less harmful emissions – Replacing your vehicle’s spark plugs can not only help increase your gas mileage on Darien roads, but completing this important vehicle maintenance step can also improve your emissions.

If you’re familiar with the Jaguar maintenance schedule, you know that changing your spark plugs every 15,000 miles or so can help to eliminate these issues entirely, ensuring better performance day-in and day-out.
