The correct plugs are listed in the owner's manual:
Spark Plugs . . . . . . . . . . . . . . . . . . . PT16EPR-C13*
(GM Part # 12561466)
Gap: 0.050 inch (1.27 mm)
*ACDelco part number.
There are not wires per-say. The car has coil-on-plug, though there is a short length of wire from each coil to each plug. I am not sure if it is replaceable or not, or if it is part of each coil. However, the owner's manual makes no recommendation to change them at any interval.
