Removing the engine cover and lift bracket make things much easier. Having headers ....a two year old could do the plugs. Having a turbo.. keep all that power in mind while you fight. It's worth it..but what a pain.
I find that pushing the metal sleeve toward the engine, then twisting to breat the boot to plug seal, then pull/wiggle works very well.
I once decided not to mess with the wires. A long screwdriver and hammer got the wires (and part of the plug off). Only downside is if a piece of the plug inside decides to break off. Ehhh I didn't worry.
