What Spark Plugs Do

They ignite the mixture of gas and air your engine burns to produce the power it runs on. Without spark plugs, your INFINITI couldn't start at all. How they do what they do is pretty straightforward. The process is called "spark ignition."

How Spark Ignition Works

Put your key in your ignition lock cylinder. Now, turn it. Your ignition switch triggers. Your car battery, plus other ignition parts like your ignition coil, starter solenoid, and starter motor, begin working together to create a small electrical charge -- a "spark."

That's where your spark plugs come in. Their leads pick up that current and use it to combust the above-mentioned fuel and oxygen. Each of your engine pistons can then pump, and your crankshaft can begin turning. Finally, the many parts of your INFINITI get moving, and it can get going.

Unfortunately, though, no spark plug lasts forever. You'll need to change yours eventually. Look for the signs it's time.

When Spark Plugs Need to be Replaced

Check your plug leads. Are they rusty, or have they widened too far? They may not be capturing charges as well. Is your engine misfiring, or has it failed? These are two other possible indicators. The worst-case scenario, however, is when spark plugs break. That often causes serious damage to an engine's cylinders.

Luckily, the spark plugs INFINITI makes get built to last -- usually, for millions of ignitions, if not up to 100,000 miles. Just don't exceed the mileage limits recommended by your owner's manual's maintenance schedule. In other words, be sure to change a spark plug before it surpasses those limits.
