I have just purchased the 4300K HID kit for my 2007 Civic. I was back and forth between 4300K & 6000K but I ended up going with the 4300K for, well, no real reason. I have friends who have the 4300K, 6000K, and I think an 8000K(?) kit and I liked the look of it the best.
Pics/Updates to come when I receive and install them.
