Several things to say about those:
1. You should not plug and play HID kits into stock housings. They need to be placed in projectors which have special lenses and cutoff shields to aim the high intensity light properly. If you don't you will blind other drivers and possibly get pulled over.
2. I have no way of knowing what the quality of those kits are. If I were you I'd check out
HIDplanet for information on projectors and ballasts.
This thread helped me decide on my current HID fog setup which I'm almost done installing.
3. The color temperature (which is the spectrum a black body would radiate if heated to that temperature) of those bulbs is listed as 10,000 K which is very dark blue. That color light is useless for practical purposes and dangerous to rely on at night. For maximum illumination you want bulbs between 4000 K and 5000 K. There are old wives tales of using yellow lights (near 3000 K) for fog lights, but those are factually incorrect. I don't feel like explaining it again, but 4300 K or 4500 K for both low beams and fogs seem ideal.
