can't believe that a boxster hasn't got HID as standard?
i've fitted HID kits to both of my bikes and they are just so much better than any incandescent bulb it's unreal. kits are coming down in price like hell. i got a single bulb H4 bi-xenon (means HID for dipped and main beam on a solenoid) for £65 delivered (would have been £100 for a 2 bulb kit)
