How Long Do Iridium Spark Plugs Last?

Do you want to know how long do iridium spark plugs last and how to make their lifespan last longer? Let’s talk about that in this article so you will also know more about the iridium spark plug’s performance in your vehicles. Continue reading below.

What are iridium spark plugs?

About Iridium

Iridium was discovered in 1803 and is one of the rare metals used in industrial applications. It exists as the 77^th number on the Periodic Table of Elements and is categorized as one of the Platinum class of metals.

Iridium is also known as the most corrosion-resistant element compared to other metals and elements. So, it can survive longer when exposed to reactive compounds in exhaust gases.

Iridium Spark Plugs

Iridium spark plug uses an iridium electrode other than regular copper electrodes. This kind of spark plug is known to last up to 120, 000 miles and the sturdiest and best performing compared to all types of spark plugs.

Compared to regular spark plugs, Iridium spark plugs are typically more expensive. However, if you want your spark plugs to last longer, as well as enhance the performance of your vehicle’s engine, Iridium spark plugs are your best choice.

How Iridium Spark Plugs Work？

The following information show how an Iridium spark plug works:

• Iridium spark plug handles the rigor of high-performance driving. It improves your vehicle’s general performance while saving fuel consumption.
• Iridium spark plug works more efficiently compared to a regular spark plug. This is due to its material composition (Iridium).
• Iridium spark plug is more resistant to corrosion or fouling than regular spark plugs. When a spark plug is filled with oil dirt, excess fuel, and other contaminants. It reduces its capacity to ignite a spark, which causes misfire.
• But Iridium spark plug is resistant to fouling which makes it perform better than regular spark plugs for a longer period of time.
• Iridium spark plug produces more consistent and powerful sparks than a regular spark plug. This is due to its smaller Iridium electrode that can accurately focus its spark and create more powerful ignition.

Also, Iridium spark plug is what a high-powered engine needs, so it can create a stronger and more powerful spark to improve engine performance.

Types of Iridium Spark Plugs

Get to know the different types of Iridium spark plugs to better understand which one you need for your vehicles.

• Iridium Tough Spark Plugs

This type of Iridium spark plug is an ultimate aftermarket plug that is suitable for daily use. It’s great for modern engines where performance is the main concern.

• Iridium Racing Spark Plugs

In racing engines, vibrations can create issues with the ignition system. This type of Iridium plug is strong enough to guarantee that vibrations cannot affect its performance. It can lessen the chances of having melted or fractured plugs.

• Iridium Power Spark Plugs

This Iridium plug is designed for basic performance.

• OE Iridium Spark Plugs

This plug is equivalent to the stock plugs built at the factory when the vehicle was built. It features a 0.6mm Iridium alloy center electrode which is equivalent to a platinum chipped ground electrode. It is designed for optimum service while enhancing performance.

• Laserline Iridium LPG Spark Plugs

This plug is designed due to increasing fuel prices of LPG (Liquid Petroleum Gas). It is intended to cover the petrol engine vehicles.

What is the lifespan of an iridium spark plug?

Most of the time, an Iridium spark plug can last for 100,000 miles or 3000-4000 hours of engine power. An iridium spark plug is designed to last longer than regular spark plugs, however, its lifespan depends on various brands.

Regardless of the brands, manufacturers recommend replacing an Iridium spark plug at a fixed schedule. This is to guarantee that the plug shows an optimal performance in burning fuel, as well as efficiency in fuel consumption and engine performance.

How to make Iridium spark plugs last longer?

When you are using an Iridium spark plug, here’s what you can do to make it last longer:

• Ensure compatibility

When replacing your spark plugs, see to it that it matches your vehicle’s specification or requirement.

• Don’t wait too long

You should replace your Iridium spark plug before the recommended limit. When you wait till it surpasses 150,000-200,000 miles, you will have a hard time pulling it out and might lead to a ruined plug.

FAQs

How often should you replace iridium spark plugs?

The exact time interval for Iridium spark plug replacement depends on considerable variables such as your vehicle manufacturer’s recommendation as well as your vehicle’s current condition and performance.

Are iridium spark plugs better than regular spark plugs?

Iridium spark plugs are more durable than regular copper spark plugs. Regular spark plugs easily wear out with longer use and need frequent replacement.

Conclusion

Iridium spark plug’s life can last longer than a regular copper or platinum plug. Iridium spark plugs are a perfect fit for better fuel combustion, corrosion/wear resistance, and durability. However, choosing the best spark plugs for you still depends on your purpose and vehicle needs.
