I use .058". Good gap for 20k intervals.

Gap will depend on your mods and plans.

From Intense's website

* Use the Autolite® 605 spark plugs (one heat range colder than stock) if you have a 3800 Series II or III engine engine with up to 6 pounds of boost. At this level, we recommend reducing the spark plug gap to .055", or .035" with nitrous oxide.
* Use Autolite® 104 spark plugs (two heat ranges colder than stock) if you have a 3800 Series II or III engine with 6 to 12 pounds of boost. At this level, we recommend reducing the spark plug gap to .050", or .035" with nitrous oxide.
* Use Autolite® 103 spark plugs (three heat ranges colder than stock) if you have a 3800 Series II or III engine with 12 to 18 pounds of boost. At this level, we recommend reducing the spark plug gap to .045", or .035" with nitrous oxide.

If it says series II supercharged on the cover and has a long blower snout its a series II...if it just say 3800 Supercharged its a series I...
also i think the exhaust ports are evenly spaced on the series II where as the series I has offset ports...

95 is a series one. Sorry.. didn't know what you drove.

Plug gap will be about the same per boost psi though. The guide should work fine for you. (You did post in the S2 area though) alien

And rear plugs are harder on Series I than Series II.

the series II plugs are cake i thought...as long as you dont let them intimidate you... the only one i had trouble with was the drivers side rear, and that i just took out without the ratchet... just make sure you use anti-seize compound on the threads...ive made that mistake before.
