How Long Do Mopar Spark Plugs Last?

Mopar spark plugs are tough to last millions of ignitions up to about 100,000 miles.

The Mopar plugs are also called extended life because of their durability. It is not always easy to detect a worn-out spark plug.

Since these plugs installation is inside the engine, it is not always simple to check them, unlike the tires and other visible parts. 

Several factors can cause your plug to fail. Some include:

#1. Oil in the Combustion Chamber

This problem is one of the spark plug-leading problems. Once oil leaks onto the combustion compartment, the spark plug head gets oily and dirty resulting in sudden failure. 

#2. Overheating 

When the spark plug head repeatedly undergoes overheating, it will lead to sudden failure of your car.

Overheating occurs due to several conditions, such as pre-ignition and a malfunctioning cooling system.

Furthermore, overheating can cause your plug electrode to wear out quickly.

#3. Carbon Build-up 

Characteristics of a carbon fouled spark plug include black, polluted dirt on the electrode and insulator top.

The accumulated carbon causes a decrease in the life span, leading to many car problems you experience.

In addition, a dirty air filter causes carbon residue deposits.

Driving at low speed, when your fuel mixture is too rich, dirty fuel injector, and lingering in your auto for a long time are also causes of carbon residue.

#4. Improper Spark Plug Gap 

The gap between the plug center and the side electrode needs to be flawlessly calibrated for your engine to function well.

If the gap setting is not accurate, it will put a lot of stress on the spark plug. 

Further, there are several signs that a faulty plug shows. These include:

#1. Rough Lingering:

Although this can signify many other problems in your car. You must eliminate faulty plugs as a possible source of rough lingering.

#2. Poor Fueling:

Poor fueling can arise due to many other issues in your car. However, a bad plug is a common reason for it.

#3. Failing engine

When speeding, there will not be enough power.

#4. Engine Surge:

This surge happens when too much air is in the fuel combination due to worn-out plugs.

Once your Mopar plug shows this problem, it’s best to take your auto to the mechanic so that he will replace them.

They will also help you inspect other ignition systems, such as the spark plug tube.
