- Iridium is known for its high melting point, making it exceptionally durable and long-lasting. In comparison to traditional spark plugs made from nickel or platinum, iridium spark plugs can withstand higher temperatures and maintain their performance for longer periods. This extended lifespan results in reduced maintenance costs and improved engine performance.
