NGK SPARK PLUG IRIDIUM CR9EIB-9 KAWASAKI KX 250 F 2021-2023

NGK Iridium spark plug with central electrode in iridium alloy, laser welded.

Iridium is a very precious metal and particularly resistant to the erosive action of sparks. Thanks to this characteristic, the NGK Iridium spark plugs guarantee a duration almost double compared to the standard spark plugs with nickel electrode.

The wear-resistant properties of Iridium make it possible to create a very small electrode with a diameter of only 0.6 mm. This entails a considerable reduction in the voltage required for the spark to strike and considerably favors the propagation of the flame front in the combustion chamber.
