It's a little painful, but about 1 hour & you'll be done.
+1, although I have always pulled the manifold to do these. If you are going to attempt this without pulling the manifold, I would definitely remove the cowl and the wiper motor.
You won't have any problems with the plug r/r itself. Your biggest challenge will be removing the manifold to gain access. Be sure to put back the ground connections in the correct spots or else you will have driveability issues.
I took this picture from the last 1MZ I did. For some unknown reason, I did not separate the TB from the manifold, so that is why the manifold is bungee corded out of the way.
