More Information

Platinum vs Iridium Spark Plugs

Sparks like to jump around to the sharpest point from the center electrode to the sharpest point of the side electrode. So these points ought to be durable to withstand constant sparking. Therefore materials like Copper, Platinum and Iridium are used to create these points.

Platinum Spark Plugs

A Platinum Spark Plug consists of platinum electrode tips (as the name suggests). The benefit of using platinum spark plugs is that due to the high melting point of platinum, it can outlast many copper and other kinds of spark plugs by a gap. But that also means it has lesser conductivity than these metals. On the plus side this leads to more stable current flow but the raw performance suffers quite a lot.

Iridium Spark Plugs

Iridium Spark Plugs are the best when it comes to handling heat. Not only do they have higher melting points than platinum and last longer but they also do not suffer from that backlash as platinum. With great conductivity, an iridium spark plug is your go-to if you want the best spark plug. But due to iridium being very expensive, the price of iridium spark plugs is naturally higher than platinum or copper.
