First time for me on the Xterra, and from what I've read here, #6 is a total PITA. Would it be worth the effort to remove the hood first?
Same, the first time psyched me out but once i did it it became fairly easy. Just gotta see what works and hope you have the right tools. But big +1 on taping socket and extensions together.I used the univeral with like 5 extensions for #6 . I ended putting my hands behind it cause the joint kind of binds up at certain angels. Super easy just took but 5 minutes. Not as hard as its made out to be. Just be careful setting the new plug in there and make sure you dont cross thread. what helped me was putting the plug in the spark plug boot and setting it in there that way and giving it a turn to catch threads.
