Genuine Mopar Spark Plugs

Your spark plugs may only have one role to play, but it's an important one. They're responsible for igniting the mixture of fuel and oxygen in your engine.

How Spark Plugs Work

This happens when you either turn the key in the ignition lock cylinder or press the start button. That causes the ignition switch to activate>, Then your car battery, starter motor, starter solenoid, and ignition coil get to work, producing a small electric charge that your plugs capture in their lead. The leads fire an arc of electricity across a gap between them, enflaming the mixture. Combustion occurs, the pistons begin pumping, and your crankshaft starts to turn.

Recognize the Signs of Failing Spark Plugs

No spark plug will last forever, however. Perhaps the gap between leads has widened too much, or maybe the leads have gotten rusty or corroded. Knowing how to spot failure is important if you want to ensure that you avoid engine problems. Look for:

• Your engine misfires
• You have trouble starting your vehicle
• Your engine idles rougher than usual
• Your "Check Engine" dash light lights up
