I know most people change to 1 range colder plugs for nitrous, and if you're staying NA then you go one range hotter. I plan on getting nitrous in the late summer. I was wonderign if I put one range COLDER plugs in prep for n2o, will my performance suffer right now until I actually get the nitrous, or will I not even feel the difference? Thanks.


Oh yeah, what do you need to gap them at with nitrous? And if I won't feel a difference with one range colder running NA for now, should I gap them like if I had nitrous or what? SOrry for the long post.

MODS:

HRC 16g turbo kit, Spearco custom FMIC, Custom IC piping, VT rebuilt engine: Custom 8.8:1 compression CP pistons, Eagle connecting rods, Melling oil pump, Clevite bearings, 370cc injectors, Vortech S-FMU, Apexi N-1 catback exhaust, AFX UDP, Autometer boost gauge, fuel pressure gauge, EGT gauge, Corbin's digital A/F gauge, Tokico Blue shocks, Tein springs (1.5" drop), 18" Konig Verdicts rims, VIS stock-style Carbon fiber hood

Go ahead and put the colder plugs. It won't hurt now even without NOS. To be safe, gap them smaller maybe around 0.036" or so.

I think 0.036" is good for nitrous. Just leave it at that. It will be fine for your stock motor too.
