Your INFINITI vehicle requires ignition for it to start. That means your factory spark plugs need to be in good working order. The process is known as “spark ignition,” and it’s what lights up the mixture of oxygen and fuel inside the engine's combustion chamber.

How Spark Plugs Work

It all starts when you either turn the key in the ignition cylinder or press the “Start” button. That causes the ignition switch to activate, which then leads to the starter motor, stater solenoid, ignition coil, and battery teaming up to produce an electric charge. Leads in the spark plug capture the charge and use it to kindle combustion.

Even the highest quality spark plugs can go bad, though. Whether they’ve become too corroded to fire properly, or the gap between the leads has widened too far to produce effective sparking, they’ll need replacing.

How to Recognize Spark Plug Problems

Signs of trouble include:

  • Engine misfires
  • Difficulty starting your vehicle
  • Rough engine idling
  • Your "Check Engine" dash light comes on

Genuine INFINITI Spark Plugs Perform Best

If you aren’t experiencing any of these problems, check your owner’s manual for your recommended maintenance schedule. You want to be sure to replace yours before they reach their maximum mileage rating. You also want to be sure to choose the right ones for your model. INFINITI designs their spark plugs to be compatible with their vehicle, delivering the guaranteed performance that you want. Our online auto parts store has yours in stock and ready to ship.
