Factory MOPAR Spark Plugs

Whatever the make and model of the vehicle you drive, its engine must burn fuel and oxygen to produce the power it runs on. However, no engine can do that on its own. It needs spark plugs to ignite them. The process is called "spark ignition."

How it works is straightforward. It starts when the vehicle's key turns in its ignition's lock cylinder. An ignition switch activates, and then the battery, starter motor, starter solenoid, and ignition coil (among other ignition parts) produce and send an electrical charge (a "spark") to the plugs' leads. They capture the electricity, and it combusts the engine's complement of air and gas, releasing said power. Finally, the engine pistons, crankshaft, and the many other parts that move the vehicle get going, and everything stays running thanks to the alternator.

Without spark plugs, though, neither car nor SUV, van nor truck could start at all. To make things worse, the former can and do fail. Luckily, there are symptoms to warn you. They include:

• Plug leads corroding or widening excessively
• The plugs having problems conducting electricity
• The engine misfiring or failing

Breakage is the worst-case scenario. Broken spark plugs almost invariably severely damage an engine's cylinders.

Otherwise, most usually last millions of ignitions, for up to 100,000 miles, and those that aren't made of copper and standard-life are often extended-life and made of platinum or iridium. Whichever your vehicle needs, depends on its model. Genuine OEM spark plugs work best either way, though, as Mopar designs them to work with your make and model specifically. Whichever you end up using, just be sure you replace them all before they reach their recommended mileage limits.
