    the only info to this question is make sure you have a good plug spanner that has different extension bars plus a swivell rachet drive. i dont think you need to remove the manifold for this easy job, sometimes its very handy to have a Gregory maintanance manual .

      You DO have to lift the manifold. I did this on our 3.5. From memory there are six or so bolts that go through the plenum that I undid and was able to move it enough to get at the plugs without disconnecting too much plumbing. I did it without the manual and found it fairly straightforward / obvious. I can look up the torque settings if you need them.

      EDIT: had a look at the workshop manual I have but it shows a different manifold on the GDI (Jap market) engines where it seems you do not have to lift it to get at the plugs. From further distand memory you are only actually lifting off the plenum chamber, with the manifold staying in place. A series of bolts down the middle of the plenum hold it in place as well as a support bracket on the side (s).
