Lynn,
I use the -9P in both lead trail 'cause I cant find any 10s or 11s without
going to the race plugs... Which I would probably get from racing beat.
But still not sure if that is the best decision or not.

The racing NGK is the 11.5 heat range. There is no decimal so it looks like
115 on the plug.
Not many equivalent heat range plugs in other brands, but in 2 cycle dirt
bikes and racing plugs for piston engines.
Here is a list from Mazdatrix
