this is the exact set i have...very very satisfied!

you'll need "H7" kit. i am using an 8000k bulb. bmw & audi factory hid's are about 4700k. (this determines the blueness of the lighting....higher the # bluer the color). a McCulloch kit (made in germany) is what i recommend.

here is the exact link and seller i went with...
