Pictures were fine for me. This post rules BTW. I didn't even know how to find the plugs until this FAQ. Car started acting up and I found cylinder 2 to be misfiring. With no experience on h-opposed engines I got it done in 90 minutes or so, and that's counting for breaks.
For what it's worth, I used the small (1/4?) ratchet and no extension to get off the coil packs on all 4 cylinders. Then a medium (3/8?) ratchet with a 3 inch extension to get out the plugs. Luckily nothing was too tight so I didn't run into trouble where I needed more leverage.
Hardest part is gapping the plugs right on the first try.
I would love to know how many hours of labor a shop charges for doing this job.
