Iridium

Improvement in the combustion through the best ignition

The new spark plug NGK IRIDIUM IX with conical cut in the lateral electrode and with fine central electrode, minimizes the extinguishing effect and allows an excellent expansion of the flame during the combustion.

Central electrode with 2 steps

The spark plug NGK IRIDIUM IX possesss a central electrode patented with two steps, providing one better characteristic of anti-carbonization under all the conditions of functioning of the engine. The two steps of the central electrode facilitate a secondary microdischarge that burns the deposited coal thus that it form.

Reduction of the required voltage

The fine central electrode and the conical cut of the lateral electrode increase the electric field strenght formed in the region of the recess, reducing the voltage required for the beginning of the flash. It is gotten thus, the one best one broken the cold and faster answers during the acceleration.
