Sparkplugs for a Bob 0-360

[gseiter]

I'm slowly gathering parts as funding becomes available and was wondering what sparkplugs folks were using with the Bob Barrows O-360. Seems like the old standby Champion REM40E should work but wonder if there is a better option. Hope to have my wings painted and hung before Thanksgiving. Weather and work permitting.

I have some Tempest UREM40Es and some RED37N plugs, the latter being what Bob delivered the engine with. There doesn't seem to be any difference that I can notice, other than that the RED37N has been discontinued with a suggested replacement of the REM40E. I found some opinions about the durability of the resistor in the Champion plugs that led me to the Tempest plugs when I had to find replacements. We'd love to see some pictures of your progress!
