Iridium Spark Plugs VS Platinum Spark plugs, Copper Spark Plugs #automobile #howto #diy #sparkplug

@carservicepro Iridium and platinum spark plugs are both high-performance options compared to traditional copper spark plugs, but they have some differences in their construction and performance characteristics: Material: The primary difference between iridium and platinum spark plugs lies in the material used for the center electrode. Iridium spark plugs have a center electrode made of iridium, while platinum spark plugs have a center electrode made of platinum. Durability: Iridium is one of the densest and most durable metals used in spark plugs. Iridium spark plugs typically last longer than platinum spark plugs. The iridium tip can withstand higher temperatures and erosion better than platinum, resulting in a longer lifespan. Performance: Both iridium and platinum spark plugs offer improved performance over copper plugs. However, some argue that iridium plugs provide slightly better performance due to their finer electrode tip, which can result in more precise and consistent spark. Cost: Generally, iridium spark plugs are more expensive than platinum spark plugs due to the higher cost of iridium as a material. Application: Platinum spark plugs are often recommended for vehicles with electronic distributor-based ignition systems, while iridium spark plugs are commonly used in modern vehicles with coil-on-plug ignition systems. In summary, while both iridium and platinum spark plugs offer improved performance and longevity compared to copper plugs, iridium plugs are...
