Spark Plug Gap
I'm getting in a set of Autolite HT0s since adding the zex wet kit. And im wondering if i need to gap them or are they good to go out of the box. If the need to be gapped what do they need to be? Anyone done this?

I put in one heat range colder and they came gapped correctly for the heat range. That said , if you want to gap them it takes a special tool. I got one before I got the plugs and found out they didn't need to be gapped , so I never used it ...

HT0s came pre-gapped for 0.045" (std plug gap). For S/C installations, it's suggested to have them gapped to 0.032" - 0.035" to prevent the park from "blowing out"... to gap the plugs you need special tool like the Vortech gapper: http://www.vortechsuperchargers.com/product.php?p=73 or just order your set of HT0s from DynoJoe... pre-gapped for what you want http://dynojoe.com/catalog/product_i...45d468f1124f1d
I'm suggesting visiting ModularFords for Nitrous plug gap specs.

I don't know much about Nox, but as with FI apps, it's good to have cooler plugs... If you're going around 50 to 75 Nox shot, all the way to 100, leave gap standard at .045" and keep timing std and use highest available octane, always. I suggest dynotuning your setup and go with "safe" A/F ratio. 11½ to 12 sounds safe to me?
