The Manual suggests to remove the exhaust manifold. A week ago, when I replaced these, I did NOT remove the manifold. I replaced the plugs in question with a couple of socket extensions however it was not easy. Getting the new plugs back in was not easy either. To get the plugs back in I used some rubber tubing, (I believe it was 3/8 inch i.D. Tubing) and inserted the spark plug firmly into the tubing so it held the plug as I lowered it into place. I was able to get it to turn a couple of times, so that I knew it wasn't cross-threaded, then pulled the rubber tubing off and finishing tightening the plug with the plug socket and extensions. Getting the plug wire back on was also difficult as I do not have a 'plug wire puller', which would have came in handy. I put a tiny bit of vasaline on the part of the plug that is 'grabbed' by the plug wire and worked it on and off a few times prior to putting into it's hole, in order to get the plug wire to go on more easily when it came time to push it on.
