what i have heard ppl say is that the with the HID's on the new headlights you got have tookin the stock lens and put them on the machalikes (aka the ones you have) but i have the same you have and i have 6K on mine take a look at my pics to see. but the reason for the lens change is due to better clear projection.
YES! go to ddm tuning.com. i just ordered the raptor kit. payed 51 bucks. and there was a mishap i was unaware of, after i ordered i got an email a few days later saying they were out of stock and that they will be in the next day or so. and later that day.... they came in to their shop, and i got a email form ups with a tracking number. hehe baller status!!!! good customer service when needed
