Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Do iridium spark plugs improve performance?
It has a high melting point, which also means that it can produce great electrodes while retaining its fine characteristics, Iridium spark plugs gives you better performance, complete combustion and excellent longevity which makes you free from change your spark plugs frequently.
Is it worth buying iridium spark plugs?
Iridium spark plugs give you even better gas mileage, performance, reliability, and longevity than double-platinum plugs. Due to the advanced material and innovative technology integrated into iridium spark plugs, these plugs are priced higher than copper and platinum options.
