COPPER SPARK PLUGS
PLATINUM SPARK PLUGS
DOUBLE PLATINUM SPARK PLUGS
Spark plugs simply known as “platinum” feature a platinum tip only, compared to “double platinum” spark plugs which feature platinum on the tips and other areas such as the ground electrodes. Some double platinum plugs may advertise a “fine wire” center core featuring one or more platinum discs inside of it. Although these represent a step up in price, double platinum spark plugs typically yield slightly higher performance with the traditional long life platinum plugs are known for.

SPARK PLUG HEAT RANGE
Tip: If you’ve modified your car for more power by upping the engine compression ratio, increasing a turbocharger’s boost, or even installing an add-on turbocharger or supercharger, you’ll benefit from hotter temperature spark plugs. Otherwise, it’s best to use factory specifications as a guideline for normal driving applications.
