This type of information is not easy to come by, but you can find every spec on your engine in a Chilton Shop Manual (chiltonsonline.com). I've had one for every car I've had, they illustrate how to perform every possible operation on your car, right down to torque specs and GM reorder part numbers. If you plan to do a lot of work on your car, you should probably look into getting their book.

Sorry I don't have the information, but I'm positive these guys do.

At cskauto.com I see it is supposed to be .060. Or at least that is what the factory preset appears to be on the pre-gapped plugs.

I've been sick lately, sorry I won't be on much.

Take a look around the drivetrain forums of www.clubgp.com. Many knowledgeable people there... Including myself... 99 Grand prix GTP - Last Post -- posted image.
