Tempest Aviation Spark Plugs – The best spark plugs at the best price’Fired in’ resistor for stable resistance value and smoother running engineZero-leakage seal encloses hot, high pressure combustion gasesDurable nickel finish offers wear and corrosion resistanceCeramic insulator provides high performance in severe operational conditionsReduced fouling and enhanced heat range controlAvailable individually or save $$$ in convenient 12 packs!High Conductivity Copper Core Center ElectrodeCopper, co-extruded inside a nickel alloy sleeve ensures outstanding heat and electrical conductivity while the nickel sleeve offers high resistance to corrosive combustion gases.Proprietary Glass Center Seal21st century “fired in” resistor replaces the multipart screw, spring, and carbon pile stack up used in competitive plugs and known to suffer from resistance value instability that can cause misfires, wasted fuel, and engine roughness.High Alumina Ceramic InsulatorHigh mechanical strength, superior dielectric properties, and proprietary protective glaze, provides high performance to conquer severe operational conditions. “Clean Collar” massive electrode “V” tip focuses heat to reduce fouling and enhance heat range control.Nickel FinishEnvironmentally preferable electrolytic nickel provides outstanding durable finish, superior corrosion protection, and extreme wear resistance.Nickel Ground ElectrodesAviation grade nickel electrode design focuses on minimizing sparking voltage requirements while maintaining specification gaps to ensure large, stable “flame kernels” for on-time ignition and complete combustion.Vacuum Infused Center ElectrodeThe proprietary vacuum infusion process seals the electrode/insulator gap providing stable heat range and superior center electrode cooling (heat flow to the insulator).Hot-Lock AssemblyIntense pressure and heat create positive, zero-leakage, shrunken in seal between insulator and shell to contain the hot, high pressure combustion cycle gases.Harness Wire ContactThe spring contact surface is smooth, uninterrupted, oxide-treated, and corrosion resistant. It’s chemically bonded to the fired-in resistor providing the ultimate harness/spark plug termination integrity and energy transfer.
