NGK Spark Plug (DPR8Z); GEN G400C

This NGK spark plug fits the Genuine G400C, and boasts all sorts of fanciful features-

 

It's designed to operate over a much wider heat range than ordinary plugs, resists carbon buildup and pre-ignition, the high alumina ceramics provide better heat transfer and electrical insulation, the solid copper core and nickel tipped electrode provide a longer life, the triple gasket sealing process eliminates the possibility of combustion gas leakage, the solid copper core allows for greater spark, the longer insulator nose prevents fouling, the corrugated ribs on insulator prevent flashover, and the zinc dipped shell prevents corrosion.

 

That should about cover it.
