What about iridium spark plugs? Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point... Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency. Iridium spark plugs allow for better combustion, lower emissions, improved fuel economy, and more horsepower. Increase fuel efficiency. If your engine is powered by worn-out spark plugs, it will not run as efficiently as intended

Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
