You will hear a lot that putting HID bulbs in your stock housing will cause a bunch of glare for on coming traffic. This is very true, but people still do it. I would suggest a projector retrofit in the heads. There is a guy in Ligjtningrodder.com that does them for a pretty good price.
BTW the lower the K rating the brighter they are. Most factory HIDs are 4100-4300. So if go with something close to that if you do go with HID bulbs in your stock housings. Which although I have done in the past I suggest against. Now that I have projectors the light output is much better and no issues with blinding on coming traffic.
