Longer insulator nose prevents fouling and ensures consistent spark. The triple gasket seal eliminates combustion gas leakage and the Zinc dipped shell prevents corrosion. It also reduces heat loss due to friction between the core and the ground electrode. The insulator is made of stainless steel, which has been tested in high temperature environments. The insulator can be used with any type of fuel. Notably, it was tested at a temperature of 250oC.
