By delving into Iridium vs Platinum spark plugs, we will learn more about your car’s electrical spark.
Did you know that an engine runs on a high-voltage spark? Yes! Fuel and pressure mix inside the engine to move the car significantly. A car engine consists of thousands of metal parts, small or large.
Manufacturers fuse these small parts to make the vehicle roar on the roads. The spark plug and ignition coil produce a high-voltage electrical spark in the engine to ignite the fuel and form combustion pressure.
This pressure inside the engine is the main reason for your smoother long drives. There are many types of spark plugs, among which iridium, copper, and platinum are at the top of the list. All these types have their pros and cons!
Iridium VS Platinum Spark Plug: Which One is the Best?
The production and use of high-voltage current take place inside the combustion chamber. A metal spark plug ignites the mixture of fuel vapor and air to start the engine.
The spark plug and ignition coil produce a high-voltage spark inside the chamber to move the car. All spark plugs have the same role of igniting the mixture inside the engine.
The different types of metals used to design spark plugs have advantages and disadvantages. Let’s talk about the pros and cons of different metal spark plugs!
1. Lifespan
Iridium spark plugs offer the longest lifespan for your vehicle. These spark plugs are well known for crossing the 50,000-mile mark without any problem.
Platinum spark plugs last a bit longer than copper plugs but do not cover 25,000 miles. This can be the main difference between iridium and platinum spark plugs. Choosing Iridium spark plugs over platinum ones would be the ultimate choice.
2. Performance
Iridium spark plugs are the most commonly used plugs nowadays. Spark plugs made from other metals can lead to a shaky engine start, while iridium plugs make ignition smoother.
Platinum spark plugs are not as reliable as Iridium plugs. This results in a jerky engine start which certainly affects the car’s performance.
3. Price
Iridium spark plugs are a bit more expensive than copper and platinum ones. These plugs may be the most widespread spark plugs on the market, but they are also very expensive. Price is another major difference when comparing Iridium and Platinum spark plugs.
Platinum spark plugs are an excellent choice when you are looking for cheap and affordable spark plugs on the market.
FAQ on Iridium and Platinum Spark Plugs
- Are Iridium spark plugs worth the higher cost?
Iridium spark plugs are generally more expensive than platinum or copper plugs. However, they often offer better performance, better fuel efficiency, and a longer lifespan.
Whether the higher cost is worth it depends on your specific driving needs and budget.
- When should I replace the iridium or platinum spark plug?
Iridium and platinum spark plugs have a longer lifespan than copper plugs. Manufacturers generally recommend replacing iridium plugs versus platinum plugs every 60,000 to 100,000 miles (96,000 to 160,000 kilometers).
However, it is essential to follow the vehicle manufacturer’s recommendations for your specific make and model.
- Can I switch between iridium and platinum spark plugs in my car?
In most cases, you can switch between the two without issue, provided they are compatible with your vehicle’s engine.
It is advisable to consult your vehicle’s manual or a mechanic to ensure the best plug type for your specific engine and driving conditions.
- Are there any disadvantages to using Iridium or Platinum spark plugs?
Although both types of spark plugs offer many advantages, their cost is higher than standard copper plugs.
Some might consider this cost a disadvantage. Furthermore, platinum and iridium spark plugs may not offer substantial performance gains in older or less demanding engines.
- Can iridium or platinum spark plugs improve my car’s performance?
Iridium and platinum spark plugs can improve ignition performance and fuel efficiency, which can lead to a slight increase in overall engine performance.
The extent of the improvement varies depending on the engine’s condition and other factors.
- Can I install iridium or platinum spark plugs myself, or should I leave it to a professional?
If you have experience replacing spark plugs and have the necessary tools, you can install iridium or platinum spark plugs yourself.
If you are unsure or uncomfortable with the process, it is best to leave the installation to a professional mechanic to avoid any potential issues.
- Do iridium spark plugs and platinum spark plugs require special maintenance or care?
Iridium and platinum spark plugs require relatively little maintenance, but it is essential to follow the manufacturer’s recommendations regarding gap specifications and replacement intervals.
Regular inspections during routine maintenance can help ensure they operate optimally. Also, avoid over-tightening when installing the spark plugs to avoid damaging the threads.
- Are there specific driving conditions where iridium or platinum spark plugs are particularly beneficial?
These spark plugs can offer benefits in various driving conditions, but they are particularly useful in modern, high-performance engines and vehicles with advanced ignition systems.
They excel in conditions requiring consistent ignition performance, such as city driving with stops and starts, highway cruising, and extreme temperatures.
In contrast, their benefits may be less pronounced in older vehicles with less demanding ignition requirements.
