Your emissions sticker on the radiator support should tell you. My 94 is .035".

For some more power you could drop in a set of Bosch Platinum +4's. No gapping on those.

More power? Can you actually feel the diff between conventional plugs and +4's? How much are they? I remember reading some tech article a few years ago saying they did not improve anything.
