99 E430 spark plug wire removal
 

This may seem trivial but I don't want to break anything. Question is - How do I remove the wires so plugs can be changed. I've never done this on a Mercedes and at a glance it doesn't resemble an american or japanese car.

Thanks much for any assistance!

Use a spark plug boot puller tool available at all auto parts stores. Benz uses a resistor plug cap that is easily destroyed if you pull on the wire.

A 17mm wrench works in a pinch as well on those M112 and M113 plug wires.

WIS procedures always list special tools required for the job.
