IMHO, HID Kits look like ass when they aren't in a projector housing. If you put it in your stock headlight, it'll be an annoying blue light driving down the road (especially with 8k...cars with HIDs from the factory come with a 4.3 temp.) I have the 4.3 in my car with projectors and it looks like a high end car from the factory. If you're set on an HID Kit, don't go over 6k...anything over that will look straight blue or even almost purple.
I also have the ISO grips and I love them. I don't really remember how they compare to stock...I only got them for looks.
