Your INFINITI vehicle's engine runs on a mixture of fuel and oxygen. It has to burn it to produce power. Spark plugs are what ignite the mix. The process begins when you turn your key in the ignition lock cylinder and the ignition switch triggers. Many other ignition parts start working together -- your car battery, a starter solenoid, an ignition coil, and a starter motor, to name a few. Together, they create an electrical charge, which your spark plugs' leads capture. The air and gas in your engine then combust, generating power, pumping your engine pistons and turning a crankshaft. Your vehicle's many parts then get moving. Without OEM spark plugs, though, your INFINITI wouldn't be able to start at all. To make matters worse, spark plugs can go bad. Their leads can corrode. Sometimes, they can widen. Both conditions can weaken the charges they capture. Engine misfires and shutdowns often result. Broken spark plugs are worse. They usually cause severe damage to an engine's cylinders. Luckily, spark plugs from INFINITI get built to last, for millions of ignitions and as many as 100,000 miles. Just be sure you change any that get too close to their recommended mileage limit. You can usually find more info about that in your owner's manual.
