OEM INFINITI Q50 Spark Plugs

The spark plugs are integral to your luxury sedan's performance. Without them, you wouldn't be able to achieve ignition, and your vehicle would be nothing more than an oversized piece of art sitting in your garage or driveway.

There's a spark plug atop each cylinder head in your engine. They combust the mixture of fuel and air inside each cylinder. How they do that is simple. When you press the Start button or turn the key in the ignition cylinder, an electrical current is sent. The plugs capture that current and transfer the electrons across a gap between their leads. That gap is precisely calibrated to deliver the optimal spark needed for combustion.

Eventually, though, even the best spark plugs can weaken, grow corroded, or lose effectiveness. When that happens, you'll need to replace yours.

Signs of failing spark plugs include engine misfires, difficulty starting your vehicle, or even repeated stalling. Any of these indicate that you should check your plugs ASAP, and replace them as needed. Even if you aren't experiencing any of these symptoms, you still want to be aware of your spark plugs' mileage ratings. Changing them before they reach the top end ensures that you'll continue enjoying consistent performance.
