      From what I know about this bulb it has the same p32-d base as all of the other OEM xenon's - which means it should fit in the base just fine.

      I believe the only difference is in the makeup of the bulb itself (on the inside)....
      So the short answer would be yes - it should fit.
      More info can be found here.

      Yes, the capsules will physically fit, but (as far as I'm aware) they require specific ballasts.

      the D4 is the Mercury(Hg)-free version of the D2. it's electrical characteristics are slightly different than the D2 (higher inrush current, longer time to get to steady state, etc.), and it does require a ballast designed specifically for it.
      also, be aware that (right now, anyway) most if not all of the Hg-free bulbs (D3 and D4) have lower light output than the bulbs containing mercury (D1 and D2).
