You would need the kit, depending on skillset some of us are hands on and some are the brains (we have a few that are both). If you feel comfortable doing the install it really isn't that bad if you have the tools. Or you can have them installed, either way there is one little thing to watch for that I found while installing mine. I had seen where a few others had to run capacitors to keep the HIDs from flickering. So I purchased a full canbus HID kit and installed only to find out the passenger light would flicker and almost strobe at times. So I purchased a set of LED headlights and installed those and the passenger side didn't work at all. Being that I work with LEDs all day at work trouble shooting was quite simple, LED lights do not work when the polarity (+ & -) are backwards. After a little probing with a meter I found the factory harness inside the headlight was reversed in the plug compared to the drivers side. Used a micro screw driver to pop the wire loose from the plug (depin) and reinstalled them in the right configuration. Yes now the LED lights worked so I removed them and hooked the HIDs back up and they also worked flawlessly since.
With HIDs if you spend under $130 for the kit you will more than likely have issues. The Mirimoto XB35 or 55 Elite for Canbus can be had for around $150 US and works flawless. If you buy a kit make sure to let them know you have H11 bulbs and need the bulb with wires attached (the plug style sticks out to far).
