ok I want move up to 8k hids would I have to buy a whole new kit or could I just get the 8k bulbs cause I hate the stock hids and I also want to convert to the hid fogs as well

If you have HIDs you can change just the bulb to a different color temperature. (to 10k- blue)

yea I want my hids bright blue I use to have 8k on my 4th gen but yea I want like true blue hids and yellow fogs
