OEM Mopar Spark Plugs

Your engine can't burn fuel and oxygen for power without spark plugs. They start the combustion process.

So, how do spark plugs work? Turn your key in your ignition lock cylinder. A switch triggers, activating many other ignition parts including your battery, starter motor, solenoid, and ignition coil. They work together to send electricity to the plugs' leads. When the "spark" reaches them, the air and gas inside your engine ignite. That releases power. Your engine pistons and crankshaft get moving, as do the many other parts that drive your vehicle.

Without spark plugs, though, no vehicle could start at all. To make things worse, even the best go bad sooner or later. For one, their leads can rust. If they widen, what might've once been weak charges will weaken further, to insignificance. Bad spark plugs result in engine misfires, if not a complete engine shutdown. Broken spark plugs, on the other hand, do worse: they can severely damage an engine's cylinders.

Luckily, those made these days are built to last, up to 100,000 miles and for millions of ignitions. Just be sure to replace any spark plug before it nears its recommended mileage limit.

The question, then, is "what spark plugs do I need?" That depends on your make and model. The genuine article works best either way.

Why Buy Genuine OEM?

Mopar manufactures them to work with what you drive specifically. The aftermarket can't always promise the same.
