Assuming you already know which coil is bad, all you need is a 5.5mm socket.

I'm not trying to butt in, just killing time. Wrenchtech answered your question. If you have a new question, you may be ahead to make a new post. If a misfire on #5, check spark--fuel and compression. Anytime you think you have a valve train issue, check compression, to start.
