Even if you’re comfortable with routine auto services like oil changes and tire rotations, you may be less familiar with other parts of your car and when to replace them—like spark plugs. So, when do you change spark plugs on your INFINITI vehicle? The general recommendation is to replace spark plugs after about 30,000 miles, but this interval can vary depending on your make and model. Be sure to check your owner’s manual for details!

Hobe Sound and Port Saint Lucie drivers wondering how often to change spark plugs can learn more from the experts at INFINITI Stuart in the guide below. If you have further questions, feel free to contact our service center to speak with a technician or check out our other online auto service how-to guides.

When Do I Change Spark Plugs? 

The spark plugs are part of the ignition mechanism, and their function involves moving high voltage currents from the ignition coil to the combustion chamber to start your vehicle. If your spark plugs aren’t operating properly, there are a few things you’ll begin to notice:

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

Benefits of Changing Spark Plugs

Not only will you avoid the issues discussed above, but by replacing your spark plugs in Jupiter, you’ll acquire a few benefits, too. Advantages of replacing the spark plugs on your new INFINITI vehicle at the recommended maintenance interval include:

  • Improved fuel economy: Worn-out spark plugs could reduce your fuel economy by as much as 30%, but replacing them will help gain that back.
  • Consistent combustion system: Spark plugs ensure the continuous production of combustion and keep your vehicle’s system running as it should be.
  • Your Vehicle Starts Smoothly: You’ll notice after replacing your spark plugs, that when you turn the key in the ignition, your vehicle starts effortlessly.
