How Often to Change Your Spark Plugs

It is generally recommended that you change your spark plugs every 30,000 miles, but that can vary depending on the requirements for your specific Honda car, truck, or SUV. The best way to determine how often you should change your spark plugs is to consult your owner’s manual. Learn more about when to replace your spark plugs in this guide from your local Aurora-area Honda dealership Fisher Honda.

When Do I Change My Spark Plugs? 

Spark plugs relay the high voltage current from the ignition coil to ignite the combustion chamber as soon as you start your vehicle. Over time the spark plugs can become fouled with carbon and you may notice issues with your vehicle’s performance such as:

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

Benefits of Changing Your Spark Plugs

Regularly replacing your spark plugs as part of your Honda maintenance schedule will help you to avoid the issues listed above, and also provide the following benefits:

  • Improved fuel economy – Worn out spark plugs can reduce your fuel economy by as much as 30%, so replacing them according to schedule will keep your Honda running efficiently on Arvada-area roads.
  • Consistent combustion system – Spark plugs help maintain the smooth and continuous combustion your vehicle needs to run at peak performance levels.
  • Smooth starting – Replacing your spark plugs will help ensure that your car starts right up when you turn the key in the ignition. 
  • Less harmful emissions – In addition to improving your mileage, regularly replacing your spark plugs helps to lower emissions.
