Plug features are as follows: 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, with added corrosion resistance.
Plug hex is 13/16" with a full length ground strap, triple gasket sealing process virtually eliminates fuel 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 and easy to read for tuning purposes.
Plugs are sold each and threads are 14mm.
