The percentage of a commodity which is recycled. A higher recycling rate may reduce risk to supply.

When it comes to heat resistance, iridium wins hands down. It has a higher melting point compared to platinum. This property makes iridium spark plugs particularly suited for high-performance vehicles that produce more heat. On the other hand, while platinum can withstand standard engine temperatures, it might not fare as well under extreme conditions. So what makes double platinum different than single platinum spark plugs? Double platinum plugs contain a platinum coating on the ground and center electrodes. With this efficient design, you have a great option for wasted spark ignition systems that are known to exert additional wear on the electrodes.

Made with a metallic element, iridium spark plugs are super durable spark plugs that ensure great efficiency and performance. They also have a high melting point. When it comes to the properties of a metal, iridium has a lot to offer. Relevant processes and technology developments in the chemicals sector from the production of chlorine, chlor-alkali and water purification, as well as BP's Cativa process (acetic acid production). Compared to copper, platinum has a slightly lower electrical conductivity. This might lead to a slightly weaker spark, which can impact engine performance in some high-performance vehicles. Platinum Spark Plugs, Cons #4: Not Suitable for All Engines

Regular car maintenance involves changing the spark plugs occasionally. This essential tune-up keeps the engine running at its best. To complete the job right, you need to know the different types of spark plugs available for your vehicle. The cheapest of the spark plug types is copper. It provides good performance but does use more voltage than the other types. Iridium is usually the most expensive, but it also provides the longest lifespan.Its melting point stands at a remarkable 700 degrees Celsius – significantly higher than that of platinum. Though platinum spark plugs are versatile, they may not be the best fit for all engine types, particularly high-performance or racing engines. In such cases, specific types of spark plugs may be recommended to achieve optimal performance. For spark plugs, the most common conductor materials are copper, platinum, and iridium. Of these, copper has been the most traditional and widely used due to its good conductivity. However, platinum and iridium have become increasingly popular in recent years due to their durability and ability to provide a consistent spark. Does Spark Plug Brand Matter No, spark plugs come in various sizes and thread pitches. While there are common sizes that many vehicles use, it’s essential to ensure you get the correct size for your specific engine to avoid issues or damage. What Are the Best Spark Plugs
