4100k, and 4300k is OEM, just maybe not for your car.
Consider getting higher color temp and sell off the bulbs as (used 1 time for testing ballast) so you don't take a major loss.
You are not taking a major loss anyways, you only spent like 60$ for pair
here is a bluer one for you from phillips:

sometimes you will find oem packed (2 white box that you've got) lesser version rated at 6000k for as low as 100$ but good luck with that, wont' find it often.
If you are willing to settle outside of Phillips/Hella/Osram, go with these:
