How do you change the number 6 spark plug on a 2000 Nissan frontier?

Answer 1

I had to use some socket extensions.

I added a long extension (guessing 8 or 10 inches) to the spark plug socket and lowered it down behind the manifold, once I found the plug, I added another extension, this one was only a few inches long, then snapped the ratchet on.

I loosened the plug, took off the ratchet, and hand loosened the plug the rest of the way, removed the short extension, then pulled long extension, socket, and plug out..

I repeated that process to put the new plug in, only, I left the rubber ring inside the socket and just added some WD-40 (use lightly on plug, not directly on rubber ring) so it would slip off and not stay on the plug once it was tight.

I also bent back the copper lines than ran along the fire wall that conveniently got in the way, popped them out of the track, and gently bent them up, when I was down, brought them back down and popped them back in the plastic track.
