I actually thought access was good when I did them on my '99 E430. I took off each coil unit from the valve covers. I took out the air cleaner housing. The only tight spot was the left rear set of plugs, but a 4" extension is just right and makes short work of that set. To pry off the boots at the plugs I used a peg board hook. I bent the two prongs that fit into the peg board for a snug fit on the boot and slid a length of 1/8" pipe over the opposite end as a lever. Worked like a charm.
