Both platinum and iridium fine-wire plugs will outperform copper-tipped plugs, but the iridium's ability to withstand high temperatures allows for a thinner plug tip. Where the single platinum plug has a platinum disc welded to the center electrode the double has a platinum disc on both the side and center electrodes. Iridium plugs make a stronger, more localized spark allowing you to run a wider gap at a given boost level. The electrodes in the spark plug conduct the electricity spark into the combustion chamber to start the car. If they're within .002 and you don't have the gapping pliers (few people do but they're inexpensive) then I would leave them alone due to the cost of Iridium plugs.

After all, the general purpose of a spark plug is to generate an electric current for igniting the compressed air and fuel in the combustion chamber. If you're looking for better conductivity and better performance, you should stick to copper spark plugs. A normal spark plug will produce chemical corrosion but the copper core reduces the high-temperature eels and reduces corrosion levels while at it. Platinum and iridium plugs also last 2 to 3 times longer than copper plugs, so there is less labor and expense involved into replacing spark plugs. What sets copper plugs apart is the nickel alloy electrode. The metal channels the high voltage from the spark plug wire through the spark plug so it can spark when it goes across the small gap between the central electrode and the side electrode. Using spark plugs below what has been recommended by the manufacturer will cause you extensive engine trouble. Usually, the ground electrode wears out before the other.
