Any power steering fluid except ATF. MB, Febi, auto parts store, etc. What FastLane sells is good stuff.

These cars have resistance in the wires or plug boots so you don't want resistance plugs. Stick to the proper Bosch Super plugs and you'll do fine. Some folks have problems with platinum plugs of any kind, even Bosch. Again, FastLane won't steer you wrong.
