I used this guide twice on my 09 Sahara. First at 73K and again at 115K. Great write up and thanks.
My idle started getting rough and then today I got a P3040 error and decided to change the plugs to see if that would fix it. As I grabbed the wire boot on #4 cylinder, it crumbled and basically failed. There is a good reason to change both of these at the same time. (for the record, I did replace my wires at 73K as well).
