Chrysler 300 Spark Plugs

Your Chrysler 300 engine couldn't run without an electrical charge to ignite the mix of fuel and air in it. Spark plugs provide that charge, in a process called "spark ignition." How the process works is easy: the key turns in the ignition lock cylinder, the ignition switch activates, and the car battery, starter motor, starter solenoid, and ignition coil get to work generating the charge. The plugs' leads capture it, combustion occurs, the engine's pistons begin pumping, and its crankshaft turns.

No spark plug lasts forever, unfortunately. Sometimes, their leads corrode or widen. This makes them less able to conduct electrical energy. If your engine is misfiring or failing, for instance, it's probably because of bad spark plugs. Broken ones, though, are a worse case: they can badly damage your engine cylinders. If you're experiencing any of these issues, inspect your spark plugs to figure out what exactly is happening, and replace any that need it.

What kind of spark plugs you need for the job, though, is straightforward. Those Mopar manufactures for your Chrysler 300 are tough enough to last millions of ignitions, up to 100,000 miles or so. In fact, many these days are "extended-life." Copper spark plugs are perfect for everyday driving, while platinum or iridium spark plugs are more durable. Whatever type you choose, don't let it exceed the mileage limits your owner's manual recommends.
