I replaced the plugs on my '01 E320 this weekend and here's my tips.
Plan time, The job's not easy.
Get a pair of long plyers that are used to squeeze 1/2" holes at the end for pulling off the plug wires.
Have a 3" socket extention and a U flex adapter. There isn't much room to work.
Pull off the "coils" or whatever they call the boxes that the plug wires connect to. You need the room to get the plug wires off of the plugs.
Spray the plug wires with a little bit of silicon and they slide on nice and easy.
I used anti-sieze on the plugs to make the next change go better.
I changed mine at 105,000, but should have done it sooner as the performance was noticable.
GOOD LUCK
