I did it on mine, 6000k 35w D3S bulb. Though I would probably go with the 55w next time. Feels like not bright enough for me.
And everyone is right, our stock one is much more expensive and better quality than aftermarket I believe. Stock price is over 600 and aftermarket I paid about 160 a pair.
Left are 6000k HID headlight and fog light, right are stock
