Before You Start:
Save yourself the hassle and go through Dave B at Southpoint Nissan for the parts. Great guy and he makes the process absolutely headache free. Also if you are replacing your ignigtion coils make sure to get the newer coils which have a grey dot on them. Part number for these were 22448-2Y000 and 22448-2Y005. Also if you didn't think to, now is a good time to replace your plugs as well. NGK Iridiums were used here. They run around $6 full price per plug.
The run down:
1. I recommend starting off with the rear coils on cylinders 1,3,5 for the sheer fact that these are the hardest to do and once you get through these the fronts are a breeze. So start out by locating the three coil harnesses. They will be grey with a green tab the you will push toward the ground inside the harnesses releasing it from the coil itself.
2. Once you have the harnesses disconnected, set them aside and you will be removing the 10mm bolts securing the coils down. Each coil has one bolt. Once you remove all three bolts, you can just pull the coils right out of the engine.
3. Now that the rear 3 coils are out you can move to the front three on cylinders 2,4,6. Start by removing the cover plate via the 4 allen screws pictured.
4. Now you should have the front three coils exposed. Remove the three harnesses as you did on the rear. Then remove the coils via the 10mm bolts, also like the rear. Then just pull the coils out.
5. You can now see the plugs inside the engine. To remove these you will want to use a spark plug socket becuase it will hold the plug which will pull it out of the engine for you when you remove the socket.
9. Installation is just the reverse of removal. Just make sure when you put the plugs in not to tighten them too much. You will only want to tighten these a little bit past finger tight.
