installation is easy. when i did my first time , took me 1 hour. you can DIY for sure. , v, `0 N& ?. d x! [$ P/ D1 t1 M3 Bi will charge extra for installation if you want me to, but i am not professional though.
if i go with stock i will need just the bulbs, thats the best for me.but i heard that not all the 4300k D2R bulbs would fit unless they are OEM. i may be wrong.... how much are the 6k?
