What is a Spark Plug?

A spark plug is an integral part of your ignition system. It produces the spark that ignites the air/fuel mixture, which creates an explosion that ultimately powers your car. Your spark plug can withstand thousands upon thousands of these explosions. However, like most things, the plug will eventually succumb to wear and tear. When it does, its efficiency in generating the spark will weaken.

A weakened spark plug could lead to several issues, such as misfires. Monitoring the lifespan of your spark plug will ensure that you can replace it before it completely wears out.

The Different Types of Spark Plugs

There are different types of spark plugs depending on their materials. These materials dictate their effectiveness and service life.

Copper Spark Plugs

Copper spark plugs are the most common you’ll find. They contain a nickel alloy in their central electrode and have the largest diameter compared to all the other types. This large diameter requires higher voltage to produce the necessary electric current.

Nickel alloy isn’t durable, so copper spark plugs have a short service life. Hence, they'll last between 10,000 to 20,000 miles.

Platinum Spark Plugs

Platinum spark plugs last longer than copper spark plugs. Their central electrode is made from a platinum disc that can generate more heat and reduce debris buildup, giving it a longer service life. While platinum spark plugs can be costly, they can last about 100,000 miles.

Double Platinum Spark Plugs

Double platinum spark plugs are found in cars with a distributor ignition using a waste spark system. This system fires the spark plug twice in the compression and exhaust stroke cylinders. Since the other plug is activated in the exhaust stroke, it’s considered “wasted."

Double platinum spark plugs are ideal for this system as they significantly reduce the wear gap between them. Due to the nature of the system, the spark plugs will wear out unevenly. The plugs in the positive polarity position will quickly wear down their ground electrode. Meanwhile, the plugs in the negative polarity position will experience more wear on their central electrode.

Iridium Spark Plugs

Iridium spark plugs have the most extended service life of all types. These can last longer than 120,000 miles or about 3,000 to 4,000 hours of engine usage. Gas quality will also affect their service life.

Symptoms of a Bad Spark Plug

Slow Acceleration

A faulty spark plug will cause your car to respond inadequately during acceleration because it can no longer provide the necessary electric pulses at high speeds.

Inferior Fuel Economy

A spark plug in its optimal form will burn the air/fuel mixture more efficiently. However, the efficiency is affected if worn out, resulting in higher fuel consumption.

Misfiring Engine

If you notice your engine sputtering, a faulty spark plug may be the culprit, as it no longer produces the spark to ignite the air/fuel mixture.

Rough Idling

A spark plug nearing the end of its life cycle will cause rough idling or even abnormal vibrations.

Difficulty Starting

Difficulty starting your car is often attributed to a faulty spark plug. In the worst cases, the engine won’t start as the spark plug is completely dead.

Frequently Asked Questions About Mopar Spark Plugs

How much does a spark plug cost?

Spark plug prices depend on their material. A regular plug will cost you less than $10, depending on where you live. High-quality plugs like platinum or iridium go for up to $25. You’ll also need to factor in how many cylinders your vehicle uses.

What’s the labor cost for a spark plug replacement?

If you want a professional to replace your spark plugs, it will cost you between $40 to $350. The cost depends on the engine you have.

For instance, a four-cylinder engine may cost you between $60 to $140. However, if your car has a V6 engine, which has six cylinders, the cost could go as high as $320 as the mechanic would need to remove the intake manifold to access the plugs.

Should I replace my spark plug wires?

Yes, the replacement time will generally depend on the type of spark plugs you’re using. For standard plugs, you’re looking at 30,000 to 40,000 miles. For high-quality plugs, they could go as long as 100,000 miles.
