P2. Why are NGK spark plugs superior? Because they are designet to attain the maximum engine efficiency in different loads and rotations. 1. It is a "super-clean thermic category spark plug". . It has a central electrode with a copper nucleus deeply inserted at the top, to dissipate quickly great amounts of heat. This feature makes it a "super-clean thermic category" spark plug, over-heat and dirty resistent.
When comparing the thermic characteristics of spark plugs with and without copper nucleus, copper nucleus spark plugs show superior resistance to heat and dirty, and offer a wider thermic functionality
2. It incorporates an isolator produced with high-tech highly pure alumina ceramics. -
It has superior isolation to high temperatures and guarantees spark
production.
3. Its robust construction guarantees an excelent combustion gas tightness. The special powders that connect the isolator with the metal slieve guarantee its perfect prohibition to prevent the escape of gases in the combustion chamber.
4. The nikel alloy built electrode end guarantees a high durability.
