Spark Plug CR9EIX NGK Iridium

The precious metal iridium is one of the hardest metals, the melting point of iridium is 2450 ° C.

Iridium is used for the electrode, its diameter is just 0.6 mm. The narrow electrode gives the spark plug the property to concentrate the ignition voltage especially.

The production process of a spark plug with such a fine and at the same time robust electrode against ignition erosion is based on laser welding.

There are a number of advantages of Iridium spark plug technology:

• an optimized electrode shape reduces the ignition voltage

• even more consistent combustion reduces fuel consumption

• the ignition properties prevent the spark plug from becoming sooty

• The high-quality iridium electrode material makes it possible to double the service intervals of the spark plug.

   

With Iridium technology you not only improve the ignition properties. In spite of a slightly higher purchase cost, the high durability of the spark plug ultimately saves you money.
