Q: I am changing the spark plugs and wires at 100000 miles, do the heat shield just on 2002 Buick Park Avenue

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
come out with the wires or are they attached in some way, do I leave them in after the wire is out or will they becoming out with the wire. Do I really need them if the wire is not near the manifold
