How Often to Change Spark Plugs

Spark plugs need to work properly for the internal combustion engine to move your vehicle forward. Without spark plugs, your vehicle won’t go anywhere because they ignite the gas-air mixture in the combustion chamber. Spark plugs literally provide the spark that moves the pistons up and down. 

Do you wonder how often to change the spark plugs in your vehicle? Experts generally recommend replacing spark plugs every 30,000 miles. But, how often you change your spark plugs may vary depending on your exact model. Check your owner’s manual for more information about your spark plugs.

When Do You Change Spark Plugs? 

Your Hyundai spark plugs work by moving the high-voltage current from the ignition coil, which is connected to one end of the component, to ignite the combustion chamber as soon as you start your vehicle. Here’s how this works. Fuel injectors atomize gasoline in the chamber, and then air gets added. The spark plugs ignite the gas by regulating the voltage from the ignition coils. The explosion pushes the pistons downward in the right order to send power to the transmission and hence the wheels to move your car forward.

If the spark plugs in your vehicle don’t function properly, you’ll notice problems in the performance of your vehicle. 

You might see issues such as the following:

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

Benefits of Changing Your Spark Plugs

So, how often to change spark plugs also depends on when they start to degrade. However, you might consider changing your spark plugs before they stop working completely with regular tune-ups at least once a year. 

Changing the spark plugs regularly helps you prevent those problems we mention but also prevents some problems later on. As you find out how often to change spark plugs as part of a preventative maintenance schedule for your new vehicle, you could receive some cost-saving benefits by taking care of this sooner rather than later.

This is what you get from new spark plugs:

• Improved fuel economy – A worn-out spark plug could reduce your fuel economy by as much as 30%. For example, if you get 20 miles per gallon, you’ll get around 14 miles per gallon. Replacing a bad spark plug can help get higher fuel economy and put your gas mileage back to where it needs to be.
• Consistent combustion system – Spark plugs continually produce combustion and leave your vehicle’s system running properly. Without a working spark plug, your combustion won’t run consistently.
• Your Vehicle Starts Smoothly – Your vehicle starts effortlessly when all of the spark plugs in your vehicle are working properly. Bad spark plugs can keep your engine idle.
• Less harmful emissions – Spark plugs help increase your gas mileage, and as such they also improve your emissions to lower your carbon footprint. You’ll see fewer trips to the gas station.
