bwahahaha..
projector nose plugs as you stated will overheat in a nitrous app. you
know that. can cause a miss. you don't want a miss with the nos going.
champion rn11 or 10's work really good (yah I know thats
an LA app). 1 step colder as you stated is not enough IMO. I burned out a few NGK's using NOS. otherwise they work fine in a stock app.
now that the pleasentries are out of the way....
