Hiya local.....
If the car is stock, stick with stock heat range on the plugs. A copper core plug tends to perform better in our cars, yet needs to be replaced more often than an iridium plug. Stay sway from platinum plugs, expecially Bosch, they get eaten quickly in our engines. Most prefer autolite or ngk. My only warning there is to be wary of the NGK's with screw on tips. Those can loosen and cause kr readings which drive you nuts.
Wires.. Autolite professionals are a nice wire, same with AC Delco's. Both last a long time.

AL606s are a fine choice, you can’t go wrong with NGK TR55s either.
As far as wires, the best wires I have ever personally used are MSD (on my car now). Also I’ve never heard a bad word said about AC Delco or NGK wires.
