NGK SPARK PLUG DCPR8E WITH LOOSE TERMINAL NUT 4339

A spark plug seals the combustion chamber. It conducts a spark that is generated in the ignition coil into the combustion chamber and provides a gap for that spark to jump across. Finally, it conducts the heat it picks up in the combustion process to the cylinder head and into the cooling system. Since 1936, NGK has built itself to be the world’s leading spark plug manufacturer. NGK’s spark plugs have a triple-gasket sealing process which helps them to withstand the roughest ride. A solid copper core increases spark and heat transfer and the longer insulating nose prevents fouling. The double dipped zinc-chromate shells resists corrosion and rusting.

Corrugated ribs help prevent flashover; high dielectric strength; proper heat transfer; works to eliminate combustion gas leakage; enhanced spark and heat transfer; improved anti-fouling; corrosion resistance.

Product Features:

• Triple gasket-sealing process virtually eliminates gas leakage past the shell
• 99% highly pure alumina silicate insulator enables use of longer insulator noses to reduce fouling
• 3-step trivalent-plating process uses silver chromate and zinc for enhanced corrosion resistance
