What is a better spark plug, iridium or platinum?
When it comes to spark plugs, the choice between iridium and platinum can be a bit confusing. Both materials offer advantages, but one may be a better fit for your vehicle. 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, making them a popular choice for modern, high-performance engines.
In addition to their longevity, iridium spark plugs also offer improved ignitability and a faster spark discharge. This can lead to better fuel efficiency, smoother idling, and improved engine performance. Iridium spark plugs are often recommended for vehicles with high-revving engines, turbochargers, or other performance modifications.
Platinum Spark Plugs
Platinum spark plugs are another popular option, offering a balance of durability and cost-effectiveness. Platinum is a more affordable precious metal compared to iridium, making platinum spark plugs a more budget-friendly choice. Platinum spark plugs can typically last between 60,000 to 100,000 miles before needing replacement.
While not as long-lasting as iridium, platinum spark plugs still provide improved performance over traditional spark plugs. Platinum spark plugs offer better corrosion resistance, improved ignitability, and a longer lifespan than copper or nickel spark plugs. They are a good choice for many standard, non-performance-oriented vehicles.
Which One is Better?
The choice between iridium and platinum spark plugs ultimately depends on your vehicle's needs and your personal preferences. Iridium spark plugs are generally considered the superior option, offering longer lifespan, better performance, and improved fuel efficiency. However, platinum spark plugs are a more cost-effective alternative that still provide enhanced durability and performance compared to traditional spark plugs.
If you have a high-performance or heavily modified vehicle, iridium spark plugs are likely the better choice. For standard, non-performance-oriented vehicles, platinum spark plugs may be a more budget-friendly option that still provides reliable performance. Ultimately, it's a good idea to consult your vehicle's owner's manual or a trusted mechanic to determine the best spark plug type for your specific needs.

Cons of Iridium Spark Plugs
- Iridium spark plugs are much more expensive than platinum and copper spark plugs.
- In terms of like-for-like performance, an iridium spark plug is on par with a good quality platinum spark plug, which is usually available for less money.
Do iridium spark plugs get better gas mileage?
Switching to iridium spark plugs can considerably improve the mileage of the gasoline vehicles on the highway. This change comes from the fact that you now have a better ignition profile to ensure the efficient burning of the fuel.
Which is better AC Delco double platinum or iridium?
Iridium spark plugs last long and perform well but cost more than spark plugs. They work well with vehicles with electronic distributor ignition systems. Platinum spark plugs don't last as long but are far cheaper and work better with vehicles that rely on waste spark distributor ignition systems.
What are the risks of iridium?
External exposure to Ir-192 can cause burns, acute radiation sickness, and even death. Internal exposure could occur only if a person were to swallow one of the Ir-192 seeds or pellets. Internal exposure from Ir-192 could cause burns in the stomach and intestines if the high-energy industrial pellets are swallowed.
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.
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 is the main disadvantage of platinum spark plugs?
The spark plugs made of other metals can result in shuddering engine start whereas Iridium plugs make the ignition smoother. Platinum spark plugs are not that reliable compared to Iridium plugs. These result in a jerky engine start that affects the performance of the car for sure.
Do iridium spark plugs make a difference?
Iridium Spark Plugs have some significant advantages over spark plugs made using other metals. They have better performance and more complete combustion than platinum-tipped spark plugs. Iridium has an outstanding longevity, so you won't have to change the spark plug so frequently.
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.
Do iridium spark plugs increase horsepower?
It can be highly beneficial for the people who stay in areas where it's necessary to catch up to the highway speeds quickly for staying safe. The spark plug manufacturers are unanimous about the fact that iridium spark plugs can considerably improve the engine power.
