MTEC MT-474 COSMOS BLUE WHITE H11 100W 4750k for Fog Lamps
MTEC MT-471 COSMOS BLUE WHITE H8 65W 4750K for Angel Eyes

I believe the H11 and H8 are standard naming convention for H.I.D globes.

The install is fairly easy, however for the Angel eyes BMW could have added about an inch to the wires to make it easier to change !! Remember not to touch the globe and be careful taking the globe out and putting it back in ...Also when transporting the globes ensure the globes are seated in the plastic retainer properly, I had them shipped to me and one globe was loose in the packaging when it arrived ,which damaged the grey painted end a slight bit.

As far as warranty it shouldn't void warranty as they are standard H8 and H11 globes.. putting a higher wattage in would probably void warranty as well as make the lights more than probably non compliant with road regulations etc.
