Oregon Spark Plugs designed for chain saw, brush cutter and lawn mower applications. Terminal pin is made of a steel wire resistant to vibrations. Its lower part is designed for connection with the seal, the upper part is used for the attachment of high voltage inlet. High content of aluminium oxide AL2O3 ensures a high insulation resistance, good thermal conductivity and mechanical strength. Shell features a high mechanical strength and surface protection from corrosion. Internal sealing washer ensures tightness of the combustion chamber and a suitable heat transfer from the combustion chamber to the shell. Centre electrode features high resistance to burn-off and optimum thermal conductivity. Ground electrode features high resistance to burn-off and optimum thermal conductivity. It has locked terminal nuts to ensure efficient connection and resistance to vibration even in extreme conditions. Ribs on insulator surface extend surface trajectory for eliminating any surface discharges. Resistive seal is mechanical connection of insulator, terminal pin and centre electrode. Also a electrical connection of terminal pin and centre electrode. Resistive seal for tightness of the combustion area. For spark plugs with radio interference elimination it provides suppression of electromagnetic radiation. There are two contact layers and one resistance layer. Sealing washer ensures tightness of the combustion chamber and a proper heat transfer from the spark plug to cylinder head. Insulator tip's shape facilitates regulation of heat removal from the combustion area. Electromagnetic and radio frequency interferences are generated at the time of the electrical discharge across the spark plug. Our resistor spark plugs are designed to suppress interferences with entertainment radio, television, digital data transmissions or any type electronic device. Box Contains ------------ 1 x Spark Plug
