if its got one electrode then good chance that its not gapped at least not for your car. if its got two or four then they are gapped. the one electrode plugs tend to cover a couple of vehicles so the gap can change. just call a local parts store that sells or carries them and ask them unless someone on here knows for sure.

Be careful when checking the gap on platinum plugs; it is very easy to damage the platinum tip. I have read and heard several times that you should use a special gapping tool made specifically for plat. plugs, but I have never seen where to buy one.
