Just did the spark plug change on my car. Didn't remove the intake, didn't have any special tools to remove the coils. All I used were two 6 mm box end wrenches and pressed them into the "groove" on the coil and pulled up. Coils came out relatively easily, even the rears. Total time spent was around 2 hours.
All in all, this was one of the easier cars I've changed plugs on.
