I haven't done a Mercedes, but on VW diesels I find those ratcheting box-end wrenches to be really helpful for this job. They're flat enough to get down where the plugs are and the ratcheting action means you only need a little bit of swing to make progress. > >> 3) Are there any pitfalls? >> Don't overtighten them. You can really shorten the life of the plugs that way.
