the "plug and play" kit is diy & easy to install. it plugs into the factory harness...and comes with xenon bulbs, ballast, relay etc...

the cost is about $300.

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

you'll need an "H7" kit. i am using an 8,000k bulb. bmw & audi factory hid's are about 4,700k. (this determines the blueness of the lighting....higher the #...bluer the color). a McCulloch kit (made in germany) is what i recommend. the 8,000k lighting is really really blue... almost too blue imo. if i could do it over... i would select a 5,000 - 6,000k kit. the improved lighting is unreal. a huge improvement.

installed in my car...here are the pics of where i mounted the hid hardware (you must have a flat surface). the relays are mounted using existing posts...i added a nut to secure relay. extra wire ties keep things nice and tightie (lots of extra wire).
