Spark plug is a fundamental component in a car. However, a question that many drivers have is which spark plugs are better, iridium or platinum, since both are available in the market, and you always want to have the best option for the vehicle. In this guide, you will know the difference between iridium and platinum spark plugs.
What is Iridium Spark Plug
Iridium spark plugs are one of the most durable plugs that possess high melting points along with great efficiency and performance. Also, the main iridium spark plugs advantage is that they are harder and more durable metal than platinum.
Since the iridium spark plug is durable, you don’t have to replace it quite often. The spark plug features a small electrode in its centre, hence the iridium spark plug uses less voltage in order to generate the current. This is why many auto experts recommend iridium spark plugs for vehicles.
Pros:
- Stronger than the platinum spark plug
- High melting point
- Durable in the long run
- Use less voltage
Cons:
- Expensive
What is Platinum Spark Plug
A platinum plug is similar to a copper plug, except that its centre electrode has a platinum disc that is soldered to the tip area. Hence, the platinum plug is more durable than copper and can last up to 16,000 km.
Platinum spark plugs generate more heat which helps in reducing the build-up of debris. If you have a new car with an electronic distributor ignition system, platinum plugs are recommended.
Pros:
- Lasts longer than copper
- Lower melting point
- Reduces the accumulation of debris
- Very cost-effective spark plug.
Cons:
- Comparatively less strong than other plugs
- Less durable
Iridium Vs. Platinum Spark Plug: What is The Difference?
Spark plugs allow the combustion process to take place inside the vehicle, and an engine will give more power if there is better combustion. This will depend on the spark that the spark plug electrodes have, therefore, the different options that exist on the market must be taken into account. Regularly, in the market, we find three basic materials that are platinum, iridium and copper.
However, there are some differences when it comes to sparking plugs. Some are more efficient and work better than others. Below you will find out what is the difference between iridium spark plugs and platinum.
Lifespan
Another major difference between iridium and platinum spark plug is the lifespan. The lifecycle of iridium spark plugs is longer than the platinum ones. These spark plugs can complete 8,000 km without an issue.
On the other hand, platinum spark plugs are a little better than copper spark plugs and can run about 4,000 km. This is one of the differences between iridium and platinum spark plugs.
Performance
When it comes to performance, iridium performs better than other spark plugs. The spark plugs that are made of other metals can cause a shaky engine; whereas, iridium spark plugs can make the ignition smoother. If you follow the proper car maintenance checklist, the iridium spark plugs can perform better for your car.
In comparison to Iridium plugs, platinum spark plugs are not very reliable. Platinum plugs can cause a jerky engine start which ultimately affects the performance of the car.
Also, you must know the life expectancy of cars parts to run the vehicle smoothly.
Melting Point
The melting point of Iridium is higher than platinum; with values around 2400 °C and 1760°C respectively. The higher melting point means that iridium caps can be hotter than platinum caps. While hotplugging is not always desirable, it is best to drive it around town.
Voltage
Another interesting advantage that iridium plugs offer is that they require less voltage for the spark to jump, and these tend to work quite well on cold days.
Cost
Since iridium spark plugs boast several advantages, they are a little pricey than the regular copper and platinum spark plugs. For instance:
- The price of a platinum spark plug starts from AED 135
- The cost of an iridium spark plug starts from AED 180
However, it is important to note here that the prices may vary considering the makes and models of the vehicle.
Now you know which is better iridium or platinum spark plugs. Thus, if you are thinking of changing your vehicle’s spark plugs, this guide will help you to know the difference between iridium and platinum spark plug. Moreover, if you are finding problem in car ignition or facing low few economy, check out the symptoms of bad spark plugs.
Besides changing spark plugs, if your vehicle needs major changes then consider buying a used car for sale in the UAE without taking a toll on your wallet.
