Tempest Aviation Spark Plug UREM37BY
Single Plug
Box of 12 PlugsOverview

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. |

Works good, doesn’t foul even on bottom side of new cylinders with all that oil and junk in there while it’s wearing in.

Are about the same length as the champion rem40e they replaced. Great for tight spots.

WE HAD BRAND NEW CHAMPS AND THEY WERE NO GOOD RIGHT OUT IF THE. BOX
Good product but took a long time to receive.
Brand new, gaps set perfectly!
Spruce pricing was best. As far as the plug goes... this design is especially good for older radials that were not designed for 100 LL. This design helps burn off the lead deposits.
Its a spark plug. It looks pretty jazzy with the shiny nickle plating. The engine runs well with them. The price (by aircraft standards) is pretty reasonable.

Yes, each plug includes a copper gasket.
Yes, this is a 18mm.
Only the brand. UREM37BY is made by Tempest, REM37BY is made by Champion. The applications are the same.
