it's really gonna' be a case of trial n' error....in a perfict world you should really have 2 sets of sparkplugs, one set for the street and the other set for when you spray it.....

I recommend Motorcraft AGSF-22-C or the new part # SP-505 gapped at .048 to .052 for the street and for the Nytrous, Id use a Morotcraft AWSFA-12-C or the new part # SP-494 gapped at .038 to .044....

now to be 100% sure you got the right plug, right gap, proper amount of fuel and the right tune, is to make a blast down the track and click the car off in hight gear, (which is tuff to-do in our cars but can be done) then coast to a stop, cool the car down and do a plug-check....

alot and too much for me to explane here, but he are a few things...
inspect the tip for damage, check the gap, look at the tip and the threads for overheating, look at the plugs porcelain for color and small tiny grey/black specks....that should get you started, you should have a sparkplug light and magnifier too and dont forget to index those sparkplugs too

also I recommend getting a book, called " The Nitrous Oxide High Performance Manual" makes for great reading....
