All You Need to Know About the Spark Plugs in Your INFINITI G37
What They are and What They Do
Their job is to ignite the mixture of fuel and air in the car's engine, in a process called "spark ignition." It starts when you turn your key in the ignition lock cylinder. An ignition switch triggers, your car battery, starter motor, starter solenoid, and ignition coil get produce a small electrical charge, the leads on the plugs capture it, and combustion occurs inside engine. As a result, its pistons pump, the crankshaft turns, and the many automotive systems throughout your vehicle start running on their own power.
No spark plug lasts forever, though. Sometimes, the plugs' leads corrode or widen too far. This affects their electrical conductivity. Luckily, if they're starting to go bad, there are symptoms that'll tell you it's time for a change.
Signs You Need to Replace Them
- A lit Check Engine light
- Hard starts
- Rough idling
- Engine misfires
- General engine underperformance
- Hesitation when accelerating
- Surging (the feeling of speeding up when you aren't)
- Worsening fuel economy
- Engine failure
Broken spark plugs are the worst-case scenario. It usually means severe and costly engine cylinder damage.
If you're having any of these issues with your car, inspect your spark plugs, changing any indicated in the results. Don't let any go past their recommended mileage limits.
