Steve and All,

Link below to "Sparkplugs.com"...........Two versions of the BR10EIX plug..........Be advised that the part # 6801 has a 

removable top terminal and the part # 6957 has a solid top terminal...........Plug was designed for motorcycle/scooter,etc

and has no listed rotary engine application........Has "Iridium" center electrode and is probably the same as the RX8

Iridium plug except for a little colder heat range...........FWIW...........($8.06 each)

Steve,

   Are these -10 plugs NGK ?.............My memory fails me as I do not recall stock -10 heat range............

I also much appreciate your unpaid and freely shared research............
