Tempest - Fine Wire Electrode Aircraft Spark Plug | URHM38S

Tempest uses the latest advances in aviation technology to continue to push forward with automation, reliability, and performance. They use the most advanced manufacturing processes and their innovative spark plug designs combined to create the "World's Best Aviation Spark Plugs"! High Conductivity Copper Core Center Electrode - Tempest spark plugs have a pure copper core that has been co-extruded inside a nickel alloy sleeve for better heat and electrical conductivity, Additionally, the nickel sleeve provides increased resistance to corrosive combustion gases. The end result is a highly resistant, longer-lasting inner tube that can withstand higher pressures and temperatures. Proprietary Glass Center Seal - The 21st century ‘fired in’ resistor is a more energy-efficient replacement for the multipart screw, spring, and carbon pile-up used by competitors. The new spark plug design improves resistance value instability which can cause misfires, wasted fuel, or engine roughness.
