How Often to Change Spark Plugs


Spark plugs are a small component in your vehicle that you probably don’t notice during day-to-day drives in Munster. But if your spark plugs are malfunctioning, the entire car can grind to a halt! So, what do your Ford spark plugs do and how often should they be replaced? Most experts recommend replacing your set every 30,000 miles or so. This will depend on your unique driving habits and your car type, so check your owner’s manual or ask our service technicians for advice. We’re always happy to help!

What are Spark Plugs?

Your Ford spark plugs are tiny components that start the process of engine combustion. They take the high-voltage current from the ignition coil and use it to ignite the combustion chamber. That means that when you turn on your vehicle for your Schererville commute, spark plugs ensure that your car starts quickly and that you get on the road in no time.

When Do You Change Spark Plugs?

So, how do you determine how often to change spark plugs? The 30,000-mile guideline is a solid rule of thumb for most drivers around Griffith. But, there are some warning signs that you might notice if you need new Ford spark plugs a little earlier than scheduled:

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

Benefits of Changing Your Spark Plugs

Now that you know how often to change spark plugs, why is it so important to replace them on schedule?

  • Improved fuel economy – Worn spark plugs cause your engine to work less efficiently. If you replace a set of old spark plugs, you can bring back your fuel economy by as much as 30%!
  • Consistent combustion system – Spark plugs allow for the continuous production of combustion, which means that your car will start smoothly every time. That means better performance from your engine and far less stress for you!
  • Less harmful emissions – Replacing worn spark plugs is great for your fuel economy, but also the environment. Fresh spark plugs produce less harmful emissions, which means you can breathe easier in Highland!
