OEM Hyundai Spark Plugs

Your Hyundai vehicle won't start without ignition. That comes thanks to the original spark plugs that were installed at the factory. The produce the initial flash, or spark, that kindles the air-fuel mix inside your engine's combustion chamber.

How Spark Plugs Work

The spark plugs are housed in the engine's cylinder head. They create that initial flash by sending an arc of electricity across the gap between their two leads. Those gaps are calibrated so that they provide the ideal sparking required for ignition.

If your Hyundai has a diesel engine, though, it doesn't have spark plugs. Instead, it features glowplugs. Those have a heating element in their tip, which ignites the fuel mist that's sprayed into the engine cylinder.

How to Spot Failing Spark Plugs

Even the best spark plugs will eventually begin to fail, whether due to age or the gap between the leads growing too large to produce an effective spark. Signs of this include:

• Your engine misfires
• The engine idles roughly
• Your fuel economy worsens
• You have trouble starting your vehicle
• The "Check Engine" dash light comes on

If you don't notice any of these, check your owner's manual for your recommended maintenance schedule. Whether your spark plugs are due for a scheduled change or are not performing right, you'll want to replace them before your car or SUV stops running. Make sure that you choose original Hyundai spark plugs, since they're the only ones made to meet your model's specifications.
