Things To Know About Ruthenium Spark Plugs

In the 4.0 technology era, technology development is an important factor contributing to innovation and replacing outdated and outdated inventions. Among them is the change of details and accessories in today’s new car manufacturers.

Ruthenium spark plugs are no exception. The use of ruthenium spark plugs will help prevent oxidation, prolong the life of the spark plugs, and improve the ignition speed of your vehicle.

What Are Ruthenium Spark Plugs?

Ruthenium spark plugs are a device that uses technology. Specifically, it helps to provide an electric spark that contributes to the combustion of the gas mixture (fuel-air). The sparks in the spark plugs must be strong enough and detected at the right time to ignite the fuel to keep the car running.

Why do people use Ruthenium technology? Because Ruthenium is a chemical element with the symbol “Ru”. In fact, Ru is inert to most other chemicals and melts at 4233 degrees F.

In its alloy form, Ruthenium is much more resistant to corrosion and oxidation than iridium or platinum. Therefore, the manufacturer took advantage of that advantage to create Ruthenium spark plugs to improve the performance quality of vehicles.

Using Ruthenium technology makes a difference for ruthenium spark plugs. Therefore, Ru spark plugs have outstanding characteristics compared to ordinary spark plugs. Here are all the attributes of Ruthenium premium spark plugs as well as their advantages.

Unlike conventional spark plugs, ruthenium spark plugs provide superior oxidation resistance and significantly reduce ignition time for your car. This has made the difference between Ru spark plugs compared to similar devices.


DFE is used for non-turbocharged and PSPE applications in turbocharged engines. Specifically, DFE has the full name of Double Fine Wire Electrode.

This type of spark plug was created to meet the increasing demands of newer engines and emissions requirements. In addition, it is also extremely flammable and has a lifespan of up to 100,000km.

The full name of PSPE is Projected square platinum electrode. Spark plugs are designed by placing an open end of platinum on the tip of a shortened grounding electrode. Therefore, PSPE allows sparking to be concentrated between the thin wire center electrode and the shining platinum earth electrode.

A smaller electrode will require less voltage, which will save fuel and horsepower for your vehicle. In addition, the small electrode also reduces the flame extinguishing process.

Better Durability

Ruthenium alloys have better wear resistance than other materials in the platinum family. In fact, Ru spark plugs have a longer life than other lead spark plugs. Its working time is 2 times longer than iridium spark plugs and 4 times longer than standard nickel spark plugs.

Higher Ignitability

Ruthenium spark plugs have high ignitability, ensuring maximum combustion of fuel. This design results in a faster gas response which improves ignition speed even in inclement weather.

When it comes to Ruthenium spark plugs, it is impossible not to mention their benefits. Accordingly, Spark Plugs give your engine many effects that contribute to improving working performance, improving starting speed, and protecting the internal details of the machine.

Benefits of ruthenium spark plugs

Get rid of rough operations

Ruthenium can provide enough fire to fuel your engine’s combustion. Therefore, the device can be smoothed through idling operations, contributing to improving the machine’s working efficiency.

Components are safe

When you replace conventional spark plugs with ruthenium spark plugs, it will minimize the possibility of fire and explosion, improve ignition speed, and several other dangers.

Increase fuel efficiency

Using abrasive sparks will reduce the engine’s performance. At the same time, it also consumes a lot of fuel, adversely affecting the user experience.

With the use of Ruthenium spark plugs, your engine will have a long service life, saving fuel while maintaining combustion. In the long run, it is an important factor to help users save money, and the engine runs smoother and is more responsive when stepping on the gas.

For ruthenium spark plugs, you need to keep a few things in mind to ensure that the spark plugs can work at their best and maximize the engine’s fuel consumption.

Some Notes When Using Ruthenium Spark Plugs

  • When using Ruthenium spark plugs, be careful about leakage voltage. Because it can cause some phenomena such as fire and explosion, making damage to the engine and internal components.
  • Regularly clean and sanitize the spark plugs to ensure the best performance of spark plugs.
  • You should replace the Ru spark plug after about 100,000 km.
  • Check plugs for proper clearance to improve motor performance. The gap ensures the correct voltage, ignites the fuel, and creates the combustion that makes the engine run.
  • Never misplace the spark plug gap, as it can damage your engine. When the gap is small, the weak spark will limit the ignition process of the spark plug. When the gap is too large, you may encounter a fire at high speed. Normally, the setting distance will be from 0.028” to 0.060′.


Frequently asked Questions

What are the best spark plugs for horsepower?

Currently, ruthenium spark plugs are considered the best spark plugs on the market. Because it improves ignition speed and is capable of operating well in harsh conditions. In addition, Ru spark plugs have extremely low wear resistance and long service life of up to 100000 km.

Do NGK Spark Plugs come gapped?

Although most spark plugs are now pre-installed, you still need to adjust the gap properly in some cases. Care should be taken to avoid bending or breaking the thin wire electrodes.

Are ruthenium spark plugs better than iridium?

In fact, ruthenium spark plugs last 2 times longer than iridium spark plugs. Therefore, many businesses now use ruthenium spark plugs for their engines. That will help the engine to operate stably for a long time without any problems.


Hopefully, the article will help you have an overview of ruthenium spark plugs. This is the best quality spark plug on the market. Because it uses Ruthenium technology to prevent oxidation, ensuring engine stability effectively. At the same time, this spark plug can work even in minus C weather with a fast ignition speed.
