Lol well the front 3 are easy, but the back ones are a real pain. You can either take off the intake manifold which is annoying or remove the hood and everything on the back side of the intake manifold to get to them. Or you could also loosen your motor mounts a little and jack the motor up and forward and you can get to them pretty easy that way. I recommend loosening the motor mounts just because its not hard and doesn't take long, but its up to you. Good luck.
