Personally, I'd recommend against it. Remember that brighter isn't necessarily better. Optics are way more important that bulb brightness. Your H7 Halogen projector was designed to work with a halogen bulb, which emits light along a long-ish filament at 360 degrees. The led bulb emits from a point, and tries to simulate 360, but is usually not quite right. Plus the intensity varies.
Lots of people perceive PnP LED bulbs as brighter, because the foreground is bright - but in reality it is far worse because it provides no distance lighting - where you really need the light (not directly in front of the car).
Also, the added length of the heatsinks/fans of these PnP bulbs may not allow you to close the dustcap.
Some options, in order of expense (most to least):
1. Purchase OEM HID headlights
2. Retrofit an HID projector/ballast/bulbs
3. LED bulbs
4. Swap in OSRAM H7 Rallye Bulbs - these are H9 bulbs re-based to H7, and produce 700 more lumen than a normal H7 bulb.
Depending on what you want to spend, I'd pursue options 1,2, or 4 before I went with an PnP LED bulb.
If your dead set on an LED bulb, I've heard not so good things about OPT7. TRS sells a newer Morimoto LED bulb (called 2Stroke) that has relatively good reviews. It's hit or miss really on how well it works - comes down to optics. Haven't heard of anyone that's tried an LED bulb in a Kia H7 Projector.
