Assuming that the engine is similar to the M113 in my CLK500, and has the metal boots over the spark plug wires, then a 17 mm spanner fits neatly behind the 'bulge' in the metal, making it easy to lever them off. A tip from member Lynall, many years ago.
Give the boot a wiggle by hand first, then slip the open end of the 17mm spanner onto the metal boot & use it as a lever to remove the boot from the plug. In fact, a 16 mm spanner is a slightly better fit, but not such a commonly available size.
I last used the technique to replace the 16 spark plugs on mine about a month ago (@175K miles). Works a treat, even with the very limited space on the rear cylinders. With practice, I can get them done in around 3 hours.
