How Often to Change Spark Plugs in Your Car

Man Holding a Spark Plug

Phoenix drivers often ask us, “When do I change spark plugs?” Usually, most drivers can change their spark plugs every 30,000 miles, whether they drive a new or used vehicle. This is a broad suggestion, though, and can change if you drive a performance car or off-road. To be sure, refer to your owner’s manual and consult the factory-trained technicians at our service center. Until then, look below for more information on how often to change spark plugs and signs they’re malfunctioning.

Indicators of a Bad Spark Plug

First, let’s talk briefly about what spark plugs do. Without working spark plugs, you can’t start your vehicle. When you attempt to start your car, spark plugs transmit the ignition coil’s voltage to the engine’s combustion chamber. You’ll probably know right away if a spark plug is bad because you’ll notice the following red flags:

  • Engine misfire
  • Rough engine operation or idling
  • Slower acceleration
  • Decreased fuel economy
  • Slow engine start or failure to start

You shouldn’t need to inspect your spark plugs very often, but other components will need more attention! Make sure to check your brake fluid on a monthly basis.

Importance of Routine Spark Plug Replacement

Replacing your car’s spark plugs will keep the engine in working order, and provide the following benefits for you and your vehicle:

  • Higher Fuel Economy– You can expect your car’s fuel economy to dwindle by as much as 30% if one of the spark plugs is worn. Regaining that percentage is only possible with a replacement.
  • Working Combustion System – Spark plugs that are in good condition will keep combustion going, so your car continues to run at its best.
  • Smoother Engine Starts – Are you having problems starting your car’s engine? If the problem is worn spark plugs, you’ll see an improvement immediately after replacement. The engine will start as if there was never a problem.
  • Fewer Harmful Emissions – One of the best ways to control the amount of harmful emissions your car releases into the air is to replace your spark plugs.
