taking out stock HID! DIY??
why the heck would you want to do that? what don't you like about it? is it not 'blue' enough for you? DON'T DO IT. You're going to lose a lot of usable light by going with a higher kelvin temp bulb, and you will eventually need glasses from your eyes being so fatigued with driving at night.
The 07 IS350 uses D4S bulbs, they are mercury free and are different than the older D2S versions that are found in other HID projector equipped cars. Most of the aftermarket higher kelvin colored bulbs are D2S (for projectors) or D2R (for reflector based HIDs). If you put one of them in your headlights, your ballasts wont run them, the bulbs would light up and then go off after 10 or so seconds. So as far as options for higher temp bulbs are considered then no you dont have any for the moment.
On the other hand your D4S bulbs are rated at 4800K, D2S are rated at 4300K . Let them color shift, which will happen after 100 or so hours of use and stick to them rather than going to higher temp. Worry about what you see on the road (performance) rather than what other drivers see (bling).
