Best Gap Size when using Nitrous! I'm planning on spraying 125 shot using a NX Wet System. I'm going with NGK's TR6 spark plugs. I want to know which is the best Gap size when using Nitrous! 
Thanks for any Info!!!!!!

i was told .038 for up to 150 wet shot on TR6, and then use TR8 or 9 with .032-,035 gap for 200+ shot (from tech guys at NX express and a couple of shops). I am using .038 TR6 for now, and will be installing NX wet kit very soon (150 to start). I have the -8 plugs allready gapped at .035 for the 200 shot. Using .030 on a 100 shot is overkill, and probably makng the idel unnecesarily rough.

remember we have coil over plug. we can get away with much larger gaps than that of an ordinary distributor style ign. .035 and lower will creat a slight idle misfire but does NOT hurt anything and you will not notice it while driving. with a 125 shot you cna get away with up to .045 but there is no noticible HP improvement over a .035 gap. i run .040 on my 175 shot with no issues.. it is up to you... all good information from previous posts... its your call..
