if it is any help I do have Beru spark plugs in my engine currently
these were purchased from Merc dealer at approx £2 per plug (non resistor types).
In Merc package and with Merc star on the porcelain.
Beru details on the metal part.
EPC list Beru and Bosch and Champion as options for 124 spark plugs, and the dealer stocks whichever is avalable at the time it seems - all marked with the star in Merc packaging.
I guess your dist cap situation would be similar from the dealer.

the definitive post perhaps? http://www.mbclub.co.uk/forums/general-discussion/102134-price-rotor-arm.html appears to come down on the side of Beru ---- if its good enough for Porsche????

I went for MB original cap and rotor following issues with Bremi. I've got Beru plugs and leads, bought from a discount place in France and all seems well.
My advice to anyone is to make sure that all HT components are of the highest quality as the M104 engine (in my case) seems to be a pretty hostile environment.
