[W126 Coupe] Spark plugs and wires

[Jonathan Hodgman]

Well, Bosch plugs Used to be the best, however Bosch has stopped making the
correct NON-resistor plug for our cars.  The new plugs instead of being a
W9DC or DC0 are now WR9DC etc, etc.. I've already pulled quite a few R plugs
out of 117/116 engines that were not running right.

I beleive the best plug on the market is the Beru, however they are a pita
to get your hands on...that being the case NGK makes a very good plus in the
correct heat range and non-resistor copper electrode.  The W9DC crosses to a
BP5ES in NGk.  There is also a champion that Mercedes approves but I'm not
such a big fan of their plugs.
