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. |
My champion plugs are fouling and their resistance is all over the place. Going to try Tempest. Better price and supposed better quality and consistency.

My first experience with Tempest spark plugs. Upon receiving 12 urem40E spark plugs I checked resistance in each plug, they were all in specifications (500 ohms to 2,500 ohms for new plugs). The lowest reading was 745 ohms and the highest was 1445 ohms, most of the plugs were around 1,325 to 1,345 ohms. The plug gaps were all within specifications (.015 to.021). I regapped all plugs (.015 to .018) and installed them in my Cessna 172 with a Continental o300 engine and they are all working fine so far (2 hours). The Champions I took out had about 500 hours on them and all were within resistance specifications and all were within erosion tolerances and all were serviceable spark plugs. If the Tempest plugs match the Champions performance, I will probably stay with the Tempest plugs due to the $10 price difference per plug ($120 total savings).

Each Tempest spark plug will come with one copper gasket. Any additional gaskets must be purchased separately.
Yes, the Tempest UREM40E is a direct replacement for the Champion REM40E. Both with work in the same applications.
18mm
The heat ranges actually overlap each other. You can use either one.
5/8 inch.
UREM38S is the fine wire version of UREM40E.
Yes, these will come pre-gapped within a certain range. The end user will need to verify with their application on what gap they are actually needing. The massive plugs are gapped .016" to .021" and the fine wire are .017 to .021".
Yes, the physical dimensions are the same for both brand plugs.
These are not. UREM37BY would be considered long reach.
Yes, they are equivalent applications and interchangeable.
