I have a set of six, new in the box Bosch FR8DC+ spark plugs. The Bosch part number for cross-reference is Bosch 7927. These are the resistor version of the F8DC4 plugs that fit in M119s, M104s, and M120s among other engines. These will certainly fit and work in M119s/M104s with zero problem, though the non-resistor plugs are preferable.
This is the RESISTOR version of the plug, and they were made in Russia. I have had them in my parts stock for around 15 years, but of course never used them.
I am happy to send them to a good home, where someone can use them, free of charge (I'll pay Priority Mail postage as well). Cost is around $2.50-3.00 per plug, to buy them new.
