^^^p/n 5820 (or r5671a-10) is what you want, i just ordered some. p/n 7993 have a projected tip which you do not want when spraying nitrous.

^Since those stickies are 5+ yrs old, I guess some didn't know, or had the right info when they were posted. Projected plugs shouldn't be on that list and the mods should've removed them a long time ago..
