Mazda OEM Spark Plugs

Refine Results

When your factory Mazda spark plugs are working right, you don't spend much time thinking about them at all. When they aren't, though, you'll notice the problems almost immediately.

How Your Spark Plugs Work

Your plugs create a flash that ignites the air-and-fuel mixture in your internal combustion engine. They do that by shooting an arc of electricity across the gap between two leads. Of course, you may drive a Mazda that's powered by a SKYACTIV-D® diesel engine. In that case, you don't have spark plugs; you have glowplugs instead. Those have a heating element in their tip. That ignites the diesel fuel mist that's sprayed into the engine cylinders, reducing the cranking time needed to start your car or SUV.

Signs of Spark Plug Problems

Your spark plugs can begin to fail, though, whether due to corrosion or the gaps widening too far to produce an effective spark. Here are some common indications that your spark plugs may be going bad:

  • Uneven engine idling
  • Engine misfires
  • Reduced fuel efficiency
  • The check engine dash light comes on

You can expect to get up to 40,000 miles of use from your original spark plugs before needing to change them out. It's best to check your owner's manual for the recommended maintenance schedule, though. You want to make sure and change them before their rated mileage so that you're not risking engine problems. Mazda plugs are the best for your model, since they're guaranteed compatible.
