The Aero Accessories Tempest UREM40E aviation spark plug includes newly designed features that will impress any aviation technician. The UREM40E is equipped with a high-conductivity copper core center electrode for extreme heat and electrical conductivity. Its nickel sleeve provides durability in addition to its resistance of combustion gasses. This spark plug?s high-alumina ceramic insulator boasts excellent dielectric properties, a proprietary protective glaze and a specially designed "V" tip which focuses heat to enhance heat control and reduce fouling.

Its vacuum-infused center electrode seals the electrode-insulator gap to provide a stable heat range and optimized center electrode cooling. The durable autolite UREM40E creates a perfect seal to contain the high pressure combustion gasses. Invest in the best spark plugs for your aircraft. Our Tempest UREM40E plugs are affordable and built to last. Spark plugs are an essential part to monitor and maintain in your aircraft?s engine; invest in the best, high-performance spark plugs for your aircraft.

  • High Conductivity Copper Core Center Electrode: Copper, co-extruded inside a nickel alloy sleeve ensures outstanding heat and electrical conductivity while the nickel sleeve offers high resistance to corrosive combustion gases.
  • High Alumina Ceramic Insulator: High mechanical strength, superior dielectric properties, 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.
  • Proprietary Glass Center Seal: 21st century 'fired in' resistor replaces the multipart screw, spring, carbon pile stack up used in competitive plugs and known to suffer from resistance value instability that can cause misfires, wasted fuel, engine roughness.
  • Nickel Finish: Environmentally preferable electrolytic nickel provides outstanding durable finish, superior corrosion protection, and extreme wear resistance.
  • Nickel Ground Electrodes: Aviation 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 Electrode: Proprietary, vacuum infusion process seals electrode/insulator gap providing stable heat range and superior center electrode cooling (heat flow to the insulator).
  • Hot-Lock Assembly: Intense pressure and heat create positive, zero-leakage, shrunk in seal between insulator and shell to contain the hot, high pressure combustion cycle gases.
  • Harness Wire Contact: Smooth, uninterrupted, oxide treated spring contact surface offers enhanced corrosion resistance, is chemically bonded to the fired-in resistor providing the ultimate harness/spark plug termination integrity and energy transfer.
