This reduces carbon buildup and can increase spark plug longevity. Temperature RangeĪll spark plugs have a temperature range that represents the ability to disperse heat. The last option, silver, is weaker than iridium and platinum plugs and is generally reserved for older, high-performance vehicles. This makes them ideal for vehicles with wasted spark ignition systems.

Although relatively inexpensive, copper spark plugs are less durable than those made with other materials and need to be replaced more often.
