when i installed my turbo on the '06, the kit told me to take the stock plugs, gap them to 30-34 thousanths, and re-install. i have since purchased a colder plug, the autolite ht0's. my question is this: do i leave them at stock since they are a colder plug, or should i gap them at .035?
Still gap them at .035 or less. I run a s/c @16psi with ht0's and I have mine gapped at .028. The Ht0 is 1 heat range colder, but you gap the plugs down so you don't get spark blow out with the increased cylinder pressure. How much boost are you running with the turbo?
