Improve your engine's fuel economy without sacrificing performance with a Denso Iridium Long-Life Spark Plug.

Denso's strength comes from its materials. Each spark plug is constructed from an unbelievably strong iridium alloy, a material unlike any other on the planet. Iridium is one of the rarest elements in the earth's crust, and its origins allegedly trace back to the asteroid that wiped out the dinosaurs. It is one of the hardest metals on the planet, and also the most corrosive-resistant. For car guys, that means Iridium is perfect for making spark plugs. It has a higher melting point than platinum and it's virtually rust proof. That's why the Denso Spark Plug is six times harder and eight times stronger than the conventional platinum plug.
