Without spark plugs, your Hyundai wouldn't be able to start, let alone run. If you're looking to learn more about them, you've come to the right place. Our auto parts store has the details.

Hyundai Spark Plugs FAQ

What Do They Do?

Your vehicle's engine runs on a mix of air and fuel, but it has to burn it, and it can't do it alone. Spark plugs are what are responsible for the ignition process, which is called "spark ignition."

How Do They Work?

The above-mentioned process starts when your key turns in the ignition lock cylinder, triggering an ignition switch. Your battery, a starter motor, a starter solenoid, and an ignition coil then work together to generate electricity. The charge travels to and gets captured by the plugs' leads, combustion occurs, the engine's pistons start to pump, its crankshaft begins to turn, and your vehicle's many systems start to run.

Sadly, no spark plug is permanent. Leads can corrode, for instance -- that is, if they don't otherwise widen too far to conduct electricity properly. They can also physically weaken. If they do, they can break, causing severe and expensive engine cylinder damage in the process.

Think yours may have problems? There are signs that'll tell you, and luckily, they usually show up before things get worse.

What are the Symptoms of Failing or Bad Ones?

They include:

  • Hard engine starts
  • Misfires
  • Issues accelerating
  • Rough idling
  • A drop in gas mileage

If you see any, inspect your engine. Replace any spark plugs indicated in the results. Otherwise, be sure to change them when your owner's manual recommends it -- before they reach their mileage limits.
