Platinum and iridium have become a buzzword for ignition durability - as good conductors of heat and electricity. Both metals also have the ability to resist chemical corrosion and electrical erosion. That is why platinum and iridium are used on the electrodes of many spark plugs today. Some plugs have a solid platinum or iridium center electrode, while others have a small button of platinum welded onto the tip of center electrode or both electrodes (single platinum vs. double platinum). Some even use an alloy of platinum and iridium in the center electrode. Platinum and iridium are … [Read more...]
4 Quick Tips About Spark Plugs
