I would just make one comment.. that 8000k, although it looks cooler because it has a more intense blue, actually puts out less light than most stock HID's. Most stock HID's come in a range of 4300k-6000k. 4300k is the most light and least color (very bright but it's also pure white), as you go up in the kelvin scale, you get more intense color, but less light on the ground. This is a common misconception and in different forums I've read about many people who went as high as 12k or 14k and were dissapointed that all they got was an HID black light. Seriously. I went with 6000k (its a very bright, light cool blue) which is a good balance, and the cutoff for most every OEM HID. Anyway, everyone here can make their own choice, based on what you want, cool color or light. I just want to make people aware. Install of any plug n play kit is very basic.
