The Sylvania Silver Stars are a perfectly fine addition to the Boxster. I've used them in all my none HID vehicles ever since they were introduced with absolutely zero problems.

All lamps (light bulbs) have a temperature rating in Kelvin which relates to the color of a flame at that same temperaure. If you look at the flame from a lighter you'll see that it's blue/white at the center (hottest) and gets progressively orange as you move out (cooler).
Interestingly, the color of lamp generally has no correlation to the amount of light (lumens). However, it can dramatically affect the perception of brightness. Most people find bluer or whiter light to be brighter than orange even when both produce the same amount of light.
