As a leader in precious metals recycling, Dingfeng Precious Metals understands the importance of choosing the right spark plug material for optimal performance, durability, and efficiency. Two of the most common precious metals used in spark plugs are platinum and iridium. But which one is better?
✅ Why Iridium Spark Plugs Are Better
Durability
Iridium has a higher melting point (2450 °C) compared to platinum (1770 °C).
This allows iridium spark plugs to resist wear better, lasting up to 120,000 miles or more, significantly longer than platinum plugs.
Performance
Iridium spark plugs feature finer electrodes, providing a more precise spark and better ignition efficiency.
This results in improved fuel economy, acceleration, and smoother idling.
Ignition Voltage Requirement
Iridium’s density and hardness allow it to generate a spark with lower voltage requirements, enhancing engine performance and efficiency.
✅ Why Platinum Spark Plugs Are Sometimes Preferred
Cost
Platinum plugs are more affordable than iridium plugs, making them a budget-friendly option.
They are also more durable than copper plugs, offering a reasonable lifespan of around 100,000 miles.
Standard Usage
For most everyday vehicles, platinum plugs provide reliable performance at a lower cost than iridium plugs.
They are suitable for cars with standard ignition systems and moderate driving conditions.
Summary: Which Is Better?
If you're looking for maximum performance, longevity, and efficiency, iridium spark plugs are the best choice.
If you need a cost-effective option with good durability, platinum plugs are suitable.
