Tempest Spark Plug URHB32E
Overview
|
MASSIVE ELECTRODE SPARK PLUG Aviation Spark Plug With the most automated manufacturing processes and the most innovative spark plug in the aviation industry. Made in USA. 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. |

The order was delivered and the items were correct as ordered. I purchased the plugs to have on board as spares just in case therefore I have not installed them.

As just one data point, Ive noticed that these Tempest plugs are lasting longer than the Champion plugs they are replacing in my TSIO-520-R engine. Specifically, the Champion plugs are failing the resistance test about 100-200 hrs sooner than the Tempest plugs.

I ordered the Tempest Plugs as a direct replacement for the Champions that were always used with my IO520. The plugs are perfect. Excellent packaging and all the gaps were correct. Performance is as expected with a slight improvement over the old Champions. Highly recommend the Tempest plugs.

The Tempest plugs come pre-gapped from the manufacturer and have a paper insert in each tube stating the gap requirements.
Yes, each Tempest Spark Plug includes one copper gasket.
These use 18 mm gaskets.
These come with gaskets but if you needed additional ones you could use part # 07-00877.
