Original Mopar Spark Plugs

Your spark plugs are responsible for igniting the air-and-fuel mixture in your engine. It starts when you turn the key in the ignition lock cylinder, or press the start button if your model is equipped with one. That causes the ignition switch to activate and your car battery, starter motor, starter solenoid, and ignition coil to generate a small electric charge that the spark plug leads capture. That leads to combustion, the pistons pumping, and the crankshaft rotating.

How to Spot Bad Spark Plugs

Spark plugs don't last forever, though. Eventually the gap between the lead can grow too wide to produce and effective spark, or the plugs could rust or corrode with age. When that happens, your engine will show results. Signs of trouble include:

• Rougher-than-normal idling
• Misfiring engine
• Trouble starting your vehicle
• The "Check Engine" dash light comes on

You don't want to make yours go beyond that if you want your engine to deliver time and again. If you are experiencing these symptoms, don't make the mistake of assuming that your alternator is at fault. Check the condition of your spark plugs first.
