Tempest aircraft spark plugs – innovative high-performance design

Tempest spark plugs are among the most innovative in the aviation industry. Built with advanced materials and manufacturing processes, they ensure stable ignition, extended service life and optimal performance in demanding engine conditions.

🔧 Key features

• High conductivity copper core – outstanding heat and electrical transfer inside a nickel sleeve, resistant to corrosive gases.
• Proprietary glass center seal – fired-in resistor replaces multi-part stacks, eliminating resistance instability and misfires.
• High alumina ceramic insulator – superior strength, dielectric properties and protective glaze, with “Clean Collar” V-tip to reduce fouling and control heat range.
• Nickel finish – durable, eco-friendly electrolytic nickel finish with excellent corrosion resistance and wear protection.
• Nickel ground electrodes – minimize sparking voltage while producing large, stable flame kernels.
• Vacuum infused center electrode – seals the electrode/insulator gap for stable heat range and cooling efficiency.
• Hot-Lock assembly – zero-leakage shrink-fit seal between insulator and shell, containing high-pressure combustion gases.
• Harness wire contact – oxide-treated spring surface, chemically bonded for maximum termination integrity and energy transfer.
