spark plug gap question

[98trans_am]

Hi i just bought a 98 trans am. Im having new plugs and wires installed tomorrow just so i know they are new. I bought msd wires and ngk tr5 spark plugs. Can these plugs just be installed as they come or do they need gapped? Thanks

I bought the NGKs for an audy n they came calibrated

If they come with the little carton piece on the plug they are calibrated
