The Best Hyundai Spark Plugs

You can't start your Hyundai without ignition. That's delivered courtesy of the original spark plugs. They generate that initial flash, or spark, that ignites the air-and-fuel mixture in your internal combustion engine.

How Spark Plugs Work

Your spark plugs generally sit in your engine's cylinder head. They send an arc of electricity across a gap between two leads. The gaps are calibrated to deliver the optimal sparking needed to fire up that air-fuel mist inside the cylinder. Then the engine pistons start pumping, the crankshaft starts rotating, and you've got the power you need to head out on the road.

What Are the Signs of Failing Spark Plugs

Look out for:

• Misfiring engine
• Reduced fuel economy
• Rough engine idle
• Difficulty starting your vehicle
• "Check Engine" light comes on
• Rough idling

Some of these symptoms may lead you to think that your alternator is going bad. Before you leap to that conclusion, examine your spark plugs. The gaps may have widened to the point that the spark has grown too weak. Perhaps they've become corroded. Whether they're due for a scheduled change or are failing to perform, you need to replace them before your vehicle stops running. Always make sure to choose original Hyundai spark plugs for your ride. They're the only ones made to meet the specifications required by your model and its engine.
