I just did mine....
my two cents worth of tips:
the passenger side was a breeze after the airbox was removed, so I won't comment on that.
but for the driver side, the thick wire harness from the fuse box near the battery can be unclipped from the C-clip that holds it above the front coil pack. then you can push it toward the motor and tuck it under the eng cover for more access (especially to the rear pack/plug)
on the driver rear pack, unclip the driver front coil pack wire harness and tuck it away towards the firewall (rear of the engine). then, once you have the rear coil pack bolt loosened all the way, rotate the coil pack 180 degrees. the wire harness plug should be now easily removable. Also, with the pack rotated like that, it wiggles out completely from the top with no issues. just be sure to put it back in the same way you take it out. I was also able to do mine without removing the battery. and the tools listed are def necessary.
