[TR] NGK plugs for TR2

[wbeech at flash.net]

Angelo,
Here is a chart that should help.  The "R" is for resistor, for what little
I know this is to keep the spark plugs from causing static  on your 60 year
old AM radio.  I am sure there are other reasons as well, but what is
important is the size and the heat range are the same.

Subject: [TR] NGK plugs for TR2

Hello List:
Trying to source some NGK plugs locally for my '2. Time to retire the old
KLGs.
  I take it that the TR2 can use the same NGK BP6HS as the TR3As, despite
the slight increase in engine performance of the 3A. Also, the NGK catalog
also lists a BPR6HS as the standard recommended plug for the TR3A. Does
anyone know if this 'new' number supersedes the old BP6HS? 
Should I still ask for an NGK BP6HS?
Thanks for any help with this one.
Angelo Graham
