Infiniti G20 Spark Plugs

The spark plugs in your INFINITI G20 are responsible for combusting the mix of air and fuel in its engine, in a process called "spark ignition." How spark ignition works starts with a key turn. Your sedan's ignition lock cylinder spins, and an ignition switch activates. Your car battery, plus other ignition parts like the starter motor, a starter solenoid, and an ignition coil, get to work producing a small electric charge. The plugs' leads capture that "spark," combustion occurs inside the engine, its pistons start pumping, and its crankshaft turns.

No spark plug lasts forever, unfortunately. Sometimes, the leads on them corrode or widen, making them less able to conduct electricity. Also, if you're dealing with engine misfires or failure, it's probably because of bad ones. Broken spark plugs, though, are worse: they can badly damage your engine's cylinders.

In such cases, an inspection can help determine what's happening. Be sure to change any plugs that need it, according to the results. What kind your G20 sedan needs is an easy question to answer: genuine INFINITI. Those your OEM manufactures for your model are tough enough to last for millions of ignitions, often up to about 100,000 miles. In fact, these types are usually referred to as "extended-life." Copper spark plugs, for instance, are great for everyday driving, while platinum or iridium spark plugs will stand up to wear better. Just don't let any surpass your owner's manual's recommended mileage limits.
