Ruthenium vs. Iridium

In the automotive world, spark plugs are an essential part of the engine. Not only do they help ignite the fuel in order to make it work, but they also have a huge impact on performance and efficiency. They have remained unchanged in a car engine.

This is because they are considered to be such an essential part of the engine. Over time, the only change has been from copper plugs to platinum and now to iridium and ruthenium spark plugs. But with so many choices, which type should you use? In this article, we will look at what ruthenium and iridium spark plugs are made of, how they work, and why one may be better than the other for your vehicle.

What Are Ruthenium Spark Plugs? 

Ruthenium is a rare, hard metal that can withstand high temperatures. It’s used in spark plugs because it resists wear and corrosion better than platinum or palladium. That means your engine will last longer and run more efficiently with these plugs.

It is used as an electrode material for the ignition system because of its resistance to wear. The electrodes made from this metal will last longer than those made from other materials like copper or steel. It has a high melting point of 4233 degrees F. However, this melting point is lower than that of Iridium spark plugs. 

What Are Iridium Spark Plugs? 

Iridium is the most durable material on earth. It’s also the densest metal in existence, and it’s a natural conductor of heat. That means that when you install an iridium spark plug, your engine will run cooler and cleaner than ever before. Plus, they last so much longer than Ruthenium spark plugs, you won’t have to worry about replacing them as often either.

With a higher melting point of 4471 degrees Fahrenheit, they can withstand high temperatures and are resistant to wear and tear. 

Which Is A Better Spark Plug?- Choosing Between Ruthenium And Iridium 

They both have advantages and disadvantages that make them better or worse depending on your needs. Do you want to know the pros and cons of these two types of spark plugs before making a decision? Keep reading! 

Ruthenium Spark Plug 

Pros 

Gives More Mileage Than Iridium Spark Plugs 

Do you want to get the most out of your car? If so, then it’s time to switch from Iridium spark plugs to Ruthenium. Iridium plugs are a popular choice for many drivers, but they don’t last as long or give as much mileage as Ruthenium plugs do. In fact, the tests show that switching from an Iridium plug to a Ruthenium one can increase your fuel efficiency by up to 20%. That means more money in your pocket and less gas wasted on the road!

Ruthenium will last about twice as long as an Iridium in terms of mileage before it needs to be replaced.

Affordable

Ruthenium Spark Plug is the recommended option, especially when you are on a tight budget. Apart from being affordable, it still gives a decent performance at such a price. 

You can buy Ruthenium Spark Plugs because they will save your money and provide good performance!

Cons 

Doesn’t Perform Well In Extreme Conditions 

The ruthenium spark plug does not work well when the engine runs at high speeds or under heavy loads. It also tends to overheat and wear out quickly, making it less desirable for use in specific engines. 

Not As Durable As Iridium Spark Plugs 

Ruthenium Spark Plugs are not long-lasting. They can wear out quickly, which will cause the spark to be weak and inconsistent. This will lead to a decrease in performance as well as an increase in gas consumption. Its average lifespan is only about 1,00,000 miles between changes.

Pros 

More Resistant To Corrosion And Oxidation

An Iridium spark plug has more platinum in it than a Ruthenium one. Platinum is used for its high melting point, which helps with durability. It also has better resistance to corrosion and oxidation. This makes them great for high-performance vehicles or those who drive in extreme conditions.

Highly Long-Lasting 

Iridium Spark Plugs are the most long-lasting spark plugs on the market. They’re designed to last up to 1,20,000 miles and can be used in any type of engine. If you want a product that will keep your engine running smoothly for years, this is it.  

Lower Voltage Requirement 

Iridium spark plugs have lower voltage requirements than other spark plugs, which means that you can run them on engines with less power. This is great for those who don’t want to spend the money or time on upgrading their engine but still want the benefits of an iridium plug.

Cons 

Expensive 

Iridium spark plugs offer great performance and last longer than other spark plugs. Therefore, it is apparent that it will be priced a bit higher than other spark plugs. With several benefits, it is worth paying for Iridium spark plugs. They will save you money in the long run. 

Bottom Line

Ruthenium and Iridium spark plugs are different in many ways, but they have pros and cons. We’ve outlined some of the key differences below to help you make an informed decision about which type is best for your car. The main difference is that Iridium plugs are more expensive.

They also have a longer life span than Ruthenium plugs, but they’re not as durable. If you’re looking for something with longevity, then go with the Iridium. But if your car has been sitting in storage for a while and needs some work done on it, then go with the cheaper option of a Ruthenium plug.
