Which spark plug is better, iridium or platinum?
When it comes to spark plugs, the two most common types are iridium and platinum. Both offer advantages, but which one is the better choice? In this article, we'll explore the key differences between iridium and platinum spark plugs to help you make an informed decision.
Iridium Spark Plugs
Iridium spark plugs are known for their exceptional durability and performance. Iridium is an extremely hard and corrosion-resistant metal, which allows iridium spark plugs to last significantly longer than traditional copper or nickel spark plugs. Iridium spark plugs can typically last up to 100,000 miles before needing replacement, compared to 30,000-50,000 miles for platinum plugs.
In addition to their longevity, iridium spark plugs also offer improved ignitability, which can lead to better fuel efficiency and engine performance. The small, fine-wire electrode of iridium plugs creates a hotter, more focused spark, allowing for more complete combustion of the fuel-air mixture.
Platinum Spark Plugs
Platinum spark plugs are a more affordable alternative to iridium plugs. While they may not last as long, platinum plugs still offer improved performance and durability over standard copper or nickel spark plugs. Platinum plugs typically last 60,000-100,000 miles before needing replacement.
Platinum spark plugs are also known for their resistance to fouling, which can occur when deposits build up on the plug's electrodes. This can help maintain engine performance and fuel efficiency over time. Additionally, platinum plugs tend to be less prone to erosion, further extending their lifespan.
Which One is Better?
Both iridium and platinum spark plugs offer significant advantages over traditional spark plugs, but the "better" choice ultimately depends on your specific needs and preferences. Iridium plugs are generally considered the superior option due to their exceptional durability and performance, but they also come with a higher price tag.
If you're looking for the longest-lasting spark plugs and are willing to invest a bit more, iridium plugs are the way to go. However, if you're on a tighter budget or don't need the absolute maximum lifespan, platinum plugs can still provide excellent performance and value.
Ultimately, both iridium and platinum spark plugs are excellent choices, and the decision will depend on your specific needs and priorities. Be sure to consult your vehicle's owner's manual or a trusted mechanic to determine the best spark plug type for your car or truck.
Should I get iridium or platinum spark plugs?
To actually answer your question, iridums are better than platinum. Iridum is a harder metal, so it holds up better than platinum for long service intervals and iridum is a much better electrical conductor than platinum, making for a better spark.
Do iridium spark plugs make a difference?
- Improved Ignition Efficiency: Iridium spark plugs have a finer electrode, which allows for a more concentrated spark.
- Enhanced Performance: The improved combustion can lead to better engine performance, including increased horsepower and torque, smoother acceleration, and improved throttle response.
Can I replace iridium spark plugs with platinum?
To find out the recommended spark plugs for your specific vehicle, check your owner's manual. If your owner's manual specifies iridium spark plugs, don't downgrade to platinum spark plugs or copper spark plugs; if you downgrade, you run the risk of poor engine performance.
What spark plug gives the most power?
Iridium spark plugs
Iridium spark plugs are the best choice. Their superior materials and construction support the high energy demands of high-performance engines and ensure the cleanest and most efficient combustion. This results in improved acceleration, better fuel efficiency, and the longest lifespan among spark plug types.
What are the best spark plugs for high mileage?
Platinum spark plugs boast longevity and resistance to fouling. Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Platinum spark plugs come in two varieties - single and double platinum.
Is iridium worth more than platinum?
Manufacturers also combine iridium with osmium to make fountain pen nibs, and to construct pivot bearings and other scientific and specialized equipment. With an average price of $4,900 per troy ounce in March 2022, iridium is more valuable than gold, silver, or platinum.
Is it worth upgrading to iridium spark plugs?
The spark plug manufacturers are unanimous about the fact that iridium spark plugs can considerably improve the engine power. The advantage is crucial when you need to navigate through difficult driving situations or climb steep slopes.
Do iridium spark plugs increase horsepower?
Iridium spark plugs have a tighter wire and burn the air fuel combination better because they have a more efficient spark. This better combustion will result in a softer engine, more efficient fuel consumption, and even a slight increase in horsepower.
What is the best spark plug for performance?
Copper spark plugs run cooler and provide more power in performance driving situations. They are often installed as original equipment in turbocharged engines and engines with higher compression ratios.
What is the disadvantage of iridium spark plugs?
Cons of Iridium Spark Plugs
The best models use two or three layers of iridium on the central electrode, whereas the cheapest models may use only one thin layer. These can be prone to cracks and impact damage, so for the best results, always invest in a double or triple coated spark plug.
