Hi, bumping an old thread here - I searched
1995 S320.
I'm lost - where are the spark plugs? I opened up the cam cover, and now what? There are some brass flat-head screws holding the gray thingies attached to the black wires (one in each, with some sort of nickel looking nubby in the other) - I can pull those wire plugs out from each grey thingy, too. I tried to unscrew one, but it started to distort so I left them alone...
Picture attached.
Thanks for your time and help!
