I found this

B stands for 14mm thread diameter
K stands for Hex size 5/8" Projected tip
R stands for resistor
7 is the heat range
E is the V-Groove Tip.
11 is 1.1 mm gap or (.044")
NGK suggest .004" decrease in gap for every +50hp. Stock gap is .044". I guess the 10 (.040") or the 9 (.036")
I guess BKR7E-9 is what I need.

Got bored and looked for some alternatives.
Autolite #3924 is the stock heat range cooper plug.
Autolite #3923 is 1 step colder
Autolite #3922 is 2 steps colder

BKR7 is gapped at .035
BKR7E-11 is gapped at .043
Tony, Since you run NA most of the time I would recomend you stay with the one step colder .043 gap. However if you ever try 100hp or more out of the nitrous I would recomend two steps colder .035 gap.
These plugs are cheep enough that you could get a set of two steps for the track and just swap them for track days.

anything over 50 and you go to 1 step colder. 100 shot you will prolly need to go to 2 step colder
