Without the spark plugs, your INFINITI G37 wouldn't create ignition. Without ignition, your engine wouldn't roar to life, since ignition's needed to kindle the mixture of air and fuel inside the combustion chamber. The process is known as spark ignition, and it all begins when you turn the key in the ignition cylinder -- though modern vehicles only require that you press the "Start" button.
How Spark Ignition Works
When you press that button or turn the key, your ignition switch activates. That compels your car's battery, starter motor, starter solenoid, and ignition coil to team up and produce a small electric charge. The spark plugs capture that charge in their leads and use it to ignite the air-and-fuel mix. That leads to engine combustion, pistons pumping, and the crankshaft rotating to deliver power.
How to Spot Failing Spark Plugs
Unfortunately, spark plugs don't last forever. They can become too corroded, or the gaps between leads may have widened too much to produce effective sparking. Signs of trouble include:
- Engine misfires
- Difficulty starting your INIFINITI G37
- Rougher-than-usual engine idling
- Engine failure
- Your "Check Engine" light comes on
If your spark plugs break, that's something to deal with immediately as they can cause damage to your engine cylinders. If you're experiencing any other symptoms, check your spark plugs to see if they're the cause of your problems.
