Changing plugs on Gen 2 V8s in C4s is a long process because you sometimes have to remove some of the inner fender splash panels to access them.

As for what you should use, if you meant what tools to use--a couple of spark plug sockets, one simple plug socket and one u-joint plug socket, a short extension and a 3/8-drive, flex-head, ratchet is probably all you need.

if you run into a problem ask a more specific question.
