Ruthenium Spark Plug Benefits
Compared to other types of spark plugs, ruthenium spark plugs have better durability and can perform better in tougher conditions. In this section, we will discuss the main reasons ruthenium spark plugs have become so popular in today’s vehicles.
1. Increased Durability and Longevity
Ruthenium spark plugs are some of the most durable spark plugs on the market. Because ruthenium is a precious metal with excellent resistance to wear, ruthenium spark plugs can easily outlast copper and even platinum spark plugs. Ruthenium is also resistant to high temperatures and oxidation, allowing it to hold up better over time.
Most vehicles today are equipped with ruthenium plugs designed to last 80,000 to 120,000 miles, depending on the driving conditions. This results in having to replace the plugs less often, which saves on maintenance costs over time.
2. Better Heat Resistance
Ruthenium spark plugs are better suited to handle high temperatures, making them especially good for today’s engines with turbocharging, high compression ratios, or direct fuel injection. High temperatures are always present in the combustion chamber, and ruthenium spark plugs withstand the heat better than platinum or copper spark plugs.
Having superior heat resistance means that electrodes are less likely to erode and become fouled, which can lead to misfires and can drastically drop an engine’s performance. It is also this feature that contributes to the longevity of the spark plug, especially under high-stress operating conditions of the engine.
3. Consistent Spark for Better Performance
Ensuring a consistent and stable spark is perhaps the most important role that a spark plug plays, and ruthenium spark plugs truly shine. This role is especially important to maintain a smooth idle, fuel efficient burns, and easy engine starts, which can be hard to achieve in colder climates. The benefits of smooth engine operation and steady ignition are important to performance, especially throttle and acceleration response.
The demanding nature of performance engines and high output turbocharged setups requires the reliable, stable ignition that ruthenium spark plugs are designed for.
4. Reduced Fouling and Misfires
Fouling occurs when operating spark plugs become too hot and when deposits build up, cause the spark plug to misfire. Misfires lead to poor engine performance by restricting efficient fuel combustion, creating high emissions and leading to an overall drop in the engine’s potential. Because ruthenium spark plugs are less prone to wear and corrosion, fouling is less likely to occur compared to copper or platinum plugs.
Because of ruthenium’s resistance to fouling, spark plugs retain their functioning ability for longer, which leads to a decreased chance of misfire and overall greater efficiency of the engine.
5. Better Fuel Efficiency
With ruthenium spark plugs, there is a heightened ability to optimize the ignition of fuel due to a more stable ignition. This leads to saving money at the gas station. When the spark plugs can ignite the fuel-air mixture within the engine, a more efficient complete combustion is achieved.
This is especially true for vehicles on a daily driving routine or long-distance commutes, where the fuel efficiency savings are significant.
