Hey there - I went ahead and installed the HIDs in my 2014 Wrx - did not modify the lens or anythings. I just wanted to point out after going to the dealership tonight I parked my wrx with aftermarket HIDs next to an STI with HIDs and we both turned our lights on and there was literally no difference in how the light projected. No scattering, doesn't turn the entire headlight area blue, it illuminates in almost a perfect line in front of the car. I had my Girlfriend drive it tonight as well (Her first time, she loved it) I was in her car with the kids (Corolla) and while behind it was not obnoxious or anything. What are the chances they used the same housing\lens this time, or maybe I found a kit that works just right, I don't know. -forgive me if this has been beaten to death, but given the fact its an 2014 - I would imagine this has not been discussed too many times.
I will see if I can snag some pics of the light against my garage tomorrow night.
