Stock wires are fine. If the wires aren't touching the headers, you should be fine. If so, you can get wires with an angled boot, or get the heat shield sleeve like this.

Stock wires fit on the ARH headers I just bought.

^What they said. And leave your plugs alone unless your due for new ones.

If you are installing headers, pull the plugs out before, it will make it easier and you won't risk breaking one off. I would replace them unless they are brand new since they're cheap, go with NGK TR55's.
