How do you get to the top-back spark plug on a 2000 Nissan Frontier 3.3l V6?

your wheel wrench kit will have 2 metal pipes with hex ends and a small steel rod. The pipes are differing length, the short one will reach the #6 plug. It will be very tight against the firewall. takes a little effort, a small mirror may help. the steel rod goes through the top end of the pipe to allow u to turn the plug wrench.
