I'd also suggest a 3/8" standard 6 point socket. It'* going to be slow. I did mine.
Coil pack needs to be moved, and the engine lift bracket needs to be loosened. Cover won't just slip past.
Alt bracket comes out, MAP bracket/EGR guard comes out. Engine lift bracket is tough to get at...again needs to be loosened. Also take off the bracket that the O2 sensor plug is clipped onto.
Here'* a Frankenbonne thread...scroll down until you see the motor. That'll give you an idea of what'* in the way.
