Mopar Spark Plugs

In order to start your vehicle, you need ignition. In order to get that, you need the spark plugs to do their job. They produce the flicker needed to burn the air/fuel mixture your internal combustion engine runs on. That flash is created when an electric arc crosses the gap between the spark plug's leads. Those gaps are precisely positioned to create the optimal sparking needed for your engine. If your vehicle draws power from a diesel engine, however, combustion isn't initiated by spark plugs. Instead, glow plugs do the job. The heating element in their tip ignites the fine mist of fuel that's sprayed into the cylinder. Whichever type of plug kicks things off, the result is the same. The engine cranks, pistons pump, and you're off.

The original plugs installed in your ride were included at the factory for one reason. They're guaranteed to work best for your model. As time goes by, even these high-quality spark plugs can start to go bad. The gaps may widen. They may begin to corrode. The result? Your engine is less efficient and may even start to backfire. Don't assume that your alternator is at fault. If you've been driving with the same spark plugs for more than 60,000 miles, it may be time to change them out for a fresh set. Just be sure to use the genuine OEM plugs that are compatible with your vehicle. Our online parts center has them in stock and ready to ship. Order today and save!
