I also did the HIRs in the highs and attempted to install HoŽn endurance bulbs in the fogs. I say attempted since one bulb broke and left glass shards in my fog housing, FML.
Funny. I tried a Philips 4300k HID kit and also did not like it. The light looked spotty and not evenly disputed which made hard to see the road surface imperfections or navigate around them. On top of that the light looked blue-sh which made it get absorbed by the dark road surface. On lighter/older pavement it was better but still had hot spots and dark spots. The end result was I couldn't see very well at night. I learned from personal experience that extra ~1000 lumens is nothing without proper focus. I ended up driving with one HID and one H9 bulb for a couple of days and in almost all occasions the H9 bulb performed better at illuminating the road. HID looked brighter when looking straight at it but it also produced a very noticeable amount of glare. I am back on H9s and am much happier with them. If I ever go the HID route again it would have to be a proper retrofit.
