Which is better iridium or platinum spark plug?

Which is better iridium or platinum spark plug?

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 make a difference?

Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. … However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.

Can I use platinum spark plugs instead of Iridium?

You can't use single platinum spark plugs or traditional copper spark plugs in these systems because the side electrodes aren't designed to handle the reverse spark. … However, you can upgrade to an iridium/platinum combination plug (an iridium center electrode with a platinum-tipped side electrode).

What is the difference between platinum and iridium?

The main difference is the material that the 'tip' of the spark plug is made of – normal ones are usually copper, whereas the other two have tips made out of platinum or iridium. … On an engine that has been modified with higher compression or more boost, it might be worth springing for platinum or iridium plugs.
