I installed a H11 4300K OEM kit in my 2009 Sonata. The original lights are H11B, a relatively new bulb configuration using "snap in lite" connection method. There aren't any aftermarket replacements for it. The best you can do is OEM replacements. The bulb format and installation guides are the same for both the H11 and H11B versions, the electrical connection is different for each. I tried several modifications to other bulbs and had some success but still wasn't happy.
Since I knew the H11 would fit, it was the logical choice from Plasma Garage. The installation went smoothly, just as your site showed. I did modify the covers that seal the back of the light assemblies. I drilled a hole to accept the grommet on the new light harnesses.
Overall a very nice product with a very easy installation.
