Ruthenium and Iridium are 2 common materials that are used to manufacture spark plugs. Electric current gets delivered from an ignition system to a spark-ignition engine\u2019s combustion chamber due to spark plugs.<\/p>\n\n\n\n

Both spark plug types bring superior performance and maximum durability to the inner combustion engine.<\/p>\n\n\n\n

Every car engine spark plug requires replacement over time. Since Ruthenium and Iridium are the 2 best spark plug options, many people can\u2019t decide which spark plug to pick.<\/p>\n\n\n\n

To help you in this regard, we created this guideline on Ruthenium vs. Iridium.<\/p>\n\n\n\n

Let\u2019s read carefully.<\/p>\n\n\n\n

What is a Ruthenium Spark Plug?<\/h2>\n\n\n\n

Spark plugs are being developed with new materials to promote more extended service life, outstanding performance, and spark transmission. The manufacturer NGK has manufactured upgraded spark plugs named ruthenium spark plugs. Precise metal ruthenium is used to make the electrodes of these plugs.<\/p>\n\n\n\n

Ruthenium is a component of the platinum group. Its symbol is Ru, and 44 is its atomic number. The melting temperature of ruthenium is relatively high: 4233\u00b0 F. But when the discussion comes about the alloy, it is much more corrosion-proof and resists oxidation effectively compared to iridium. As a result, it becomes a significant choice to\u200c \u200cuse\u200c \u200cin\u200c \u200celectrical\u200c \u200ccontact\u200c \u200cto\u200c \u200cmake\u200c \u200cthem\u200c \u200cwear-proof. \u200c<\/p>\n\n\n\n

What is Iridium Spark Plug?<\/h2>\n\n\n\n

Iridium spark plugs are one of the best spark plugs on the market. Iridium spark plugs offer impressive combustion, lesser emissions, enhanced fuel economy, and extra horsepower. When you replace your car\u2019s faulty plugs with iridium spark plugs, the engine will perform smoothly and doesn\u2019t need much effort to keep the combustion process going.<\/p>\n\n\n\n

Remember, an inferior spark plug will damage the other components of your vehicle. Iridium spark plugs are the best in their class and last up to 60,000 miles. Even some iridium spark plugs offer benefits for at least 120,000 miles, based on the vehicle. Overall, iridium spark plugs are the ideal choice for use on high-performance engines.<\/p>\n\n\n\n

What are the Key Differences Between Ruthenium and Iridium?<\/h2>\n\n\n\n

Ruthenium and iridium have similarities and dissimilarities both. Although they do the same job, one is better than the other in a few points of view.<\/p>\n\n\n\n

Here we are going to share the key differences between ruthenium and iridium.<\/p>\n\n\n\n

Design<\/h3>\n\n\n\n

Ruthenium spark plugs come with 2 different designs named: double fine electrode and projected square platinum electrode.<\/p>\n\n\n\n

Characteristically, both designs are used for different purposes.<\/p>\n\n\n\n

DFE or double fine electrode maximizes the ignitibility. Also, minimizes discharges for low heat engines. It is ideal for the applications of non-turbo. Moreover, the PSPE or a projected square platinum electrode is suitable for supercharged and turbo engines.<\/p>\n\n\n\n

While iridium spark plugs don\u2019t come with a separate design.<\/p>\n\n\n\n

Durability<\/h3>\n\n\n\n

In terms of Durability, ruthenium is a CHAMPION!<\/p>\n\n\n\n

As per NGK, ruthenium spark plugs life span is more than the platinum family\u2019s other materials. More importantly, ruthenium lasts a long 2X compared to iridium spark plugs.<\/p>\n\n\n\n

More importantly, ruthenium is a better performer than iridium in harsh weather.<\/p>\n\n\n\n

High Ignitability<\/h3>\n\n\n\n

High ignitability is a remarkable feature of ruthenium. Maximum combustion is guaranteed in order to ensure better acceleration and faster fuel response and complete fuel burn as a result of a cold start. Due to the faster cold-start, your car exhaust will release less raw gas in the opening minutes of the beginning of the engine.<\/p>\n\n\n\n

Iridium responds faster to the operation of the throttle, and thus immediate improvement happens to your car engine\u2019s acceleration profile. You will experience the difference without losing time.<\/p>\n\n\n\n

Fuel Efficiency<\/h3>\n\n\n\n

No confusion that old spark plugs will be less efficient than the fresh ones.<\/p>\n\n\n\n

Without any hesitation, use a ruthenium spark plug in your car. When you use ruthenium, be sure that your vehicle will need less effort to continue the combustion process. As a result, your vehicle’s fuel efficiency will improve in the long run.<\/p>\n\n\n\n

On the other hand, due to the improved ignition profile, iridium also helps to improve the fuel economy of your vehicle when driving in the city or highway. However, the efficiency rate is not as high as ruthenium.<\/p>\n\n\n\n

What Are the Benefits of Ruthenium and Iridium?<\/h2>\n\n\n\n

Learning about the benefits of ruthenium and iridium, you will be able to make your decision accurate.<\/p>\n\n\n\n
