Bill's advice is right on the money.
One last bit I'd suggest: If you drive regularly at a higher elevation (in which case it would run a little richer), I'd try to match something up to the hotter original plug. Oh, and double-check the reach to make sure that the electrode is in the same location relative to the plug as it is on the original plug.
