OEM Hyundai Spark Plugs

Spark Plugs: Everything You Need to Know

Your engine may burn fuel and oxygen to generate its power, but it can't do that on its own. It needs spark plugs to start the process.

How They Work

Turn your vehicle's key in its ignition's lock cylinder. The ignition switch triggers, and ignition parts like your battery, starter motor, solenoid, and ignition coil work together to send an electrical charge to the plugs' leads. When the "spark" reaches them, the air and gas inside your engine combust. That releases power. Your engine pistons, crankshaft, and the many other parts that move your Hyundai get going, and so do you.

Without spark plugs, though, no Hyundai could start at all. To make things worse, they go bad sooner or later. Luckily, there are symptoms that'll warn you.

Signs They're Failing

Look for:

• Their leads decaying or widening excessively
• Weakening electrical conductivity
• Engine misfires
• Complete engine shutdown

A broken spark plug, on the other hand, is extremely dangerous to an engine: it usually damages the cylinders severely.

How Long They Generally Last Otherwise

The spark plugs Hyundai makes today are built to last millions of ignitions, for up to 100,000 miles. Those that aren't regular copper are otherwise extended-life platinum or iridium. Whichever you end up using, be sure to replace them as they near their recommended mileage limits.

What Your Hyundai Needs

That depends on your model. Genuine ones work best either way, however.

Why You Should Buy Genuine OEM

Hyundai vehicles and auto parts are designed alongside one another, to work with one another. That's not something every aftermarket brand can necessarily say.
