NGK Iridium

For many years NGK spark plugs have fitted racing engines all around the world. NGK has become an icon in spark plug technology and offers competitors a high quality product that leads them to victory. Motorsport professionals push their vehicles to the limit. Each NGK spark plug is thus developed to withstand the most severe mechanical and thermal conditions, associated with the high speeds and compression ratios of competition engines. By choosing NGK, you are assured of the world’s leading spark plug technology.

In order to withstand the extreme conditions of competition engines, NGK Iridium spark plugs offer the following characteristics:

• The fine Iridium tip ensures great durability and an always constant spark.
• Iridium alloy has a very high melting point, ideal for modern high performance engines.
• A trivalent metal protection with anti-corrosion and anti-seizure properties.
• Exceptional acceleration, high fuel efficiency and longevity.
• An ultimate design, combining technology and performance.

Iridium NGK spark plugs use the most advanced technical solution on the market. They have a fine Iridium tip on the central electrode, laser-welded using a special process. Iridium is a precious metal and one of the strongest materials in the world. It begins to melt from 2450°C and resists the electrical erosion created by the spark particularly well. The life of an Iridium spark plug is 2 times longer than that of a standard spark plug.
