NGK Platinum Spark Plugs

NGK is the largest original equipment supplier of platinum spark plugs in the world. Companies like General Motors, Honda, Nissan, Toyota, and others all specify NGK Platinum Spark Plugs as standard equipment.

Today, all of the U.S. automakers have begun to specify platinum spark plugs as original equipment. Platinum spark plugs last much longer than conventional spark plugs and perform more consistently over the course of their service life.

While platinum is an extremely durable material, that durability comes with a price. Platinum is an expensive precious metal, costing in the neighborhood of $400 an ounce. At NGK we use a large amount of platinum in our spark plugs. That large amount of platinum is naturally going to cost more. We think it's worth it.
