Inspiring....

Given that we dont know squat about your specs past your the one liner above....
and have no idea how your running your rig.....or how well its tuned....or what plugs are in it now...or what you are experiencing......

R5671A-7

FR5-1 = stock equivalent
BKR6E or BKR6EIX (iridium) = 1 step colder
BKR7E or BKR7EIX (iridium) = 2 steps colder

i know autolite has a plug thats 3 steps colder (not sure of number) and id assume thats what ya need. isnt the rule of thumb...for every 100shot of nitrous its 1 step colder. i dont know what the S/C does to that equation though

i might have that plug # at home. but im sure you can call them or go to Spark plug, Spark plug wire, spark plug gap, spark plug cross reference and ignition wires at Sparkplugs.com or something and find out
