Changing spark plugs on ML 320

Has anyone ever replaced the spark plugs on an ML 320? Anyone know of any free site or available book that can be purchased to walk me through this? Any items (such as air cleaner) that have to be removed? Any special tools needed? Thanks, Perry

If you can not find info here
then go to the other excellent sight mercedesshop.com forum.

I have not done mine yet but have 105,000 and plan to this fall. There is plenty written on it.

I suggest you to get a Factory Mercedes Manual.

It has all service and maintenance instructions, step by step.

A great help, hope this will help you.
