Tempest Spark Plug Urem40e

aviation spark plugs are required to operate in extreme conditions that's why tempest is very precise in its manufacturing processes and selection of materials and its assembly facility in Gibsonville North Carolina tempest sparkplug start out as high strength steel bars computer-controlled machines shape the steel to precise dimensions followed by quality control inspectors who check the parts or conformity to design these parts become the metal shells and sleeves that form the exterior part of the sparkplug the heart of every aviation sparkplug is the insulator and center electrode tempest electrode assemblies employ a proprietary solid-state fired and resistor the 21st century design ensures consistent resistance values throughout the life of the sparkplug spark plugs should be rejected if their resistor value measured between the wire terminal and the firing end of the center electr
