Spark Plugs
 

The spark plugs are under that black piece of plastic on your valve cover.

104 / straight six right? If so they are in the very top of the engine - have to take the cover off, must be six or eight allen bolts, after getting the air intake out of the way.

Careful, careful putting those bolts back in. The holes in the valve cover (aluminum) strip very very easily. Sometimes when you take the bolts out, all the aluminum thread will come out with the bolt. I have reactive and proactive Helicoils all over that area of both my W202 I6 engines.
