License Plate Intake Mod Help
I recently installed a C7 Carbon vented front splitter. Knowing this would overall decrease the air flow for cooling through the radiator, I pre-planned doing this license plate intake mod to counteract.
My question is, I know you have to cut the hole in the bumper, but is there anything else behind the bumper that needs to be cut? Radiator shroud? Does anyone have photos of this process?
You'll have to modify the radiator shroud to get airflow to it. It is sealed from the bottom in relation to where your air filter sits, which is where the license plate mod opens up to. You would want some sort of duct to direct are straight at the radiator so that it doesn't all just escape into the rest of the engine bay

I would rethink your plan here. Directly behind the license plate is the frame. There is a slight gap that you could fit a low profile cooler at an angle (so about 6-7 inches height) but not much room for airflow to your radiator b low the frame. Also this would require cutting the diffuser portion of the radiator shroud to allow air in. It's best to avoid that because the radiator shroud is designed to have a small opening and large expansion diffuser (Traingular shape) which slows down the air allowing the radiator to work more efficiently. If you cut a hole in the center of the lower portion of the diffuser shroud you will disrupt at least some of the airflow to your radiator as it makes turbulent air when colliding with the air from underneath. This will reduce your radiators efficiency. It may not be much of an issue until you get faster and start to push coolant temps but it is best to avoid that situation if you can plan around it. If I were you I would make a better duct to direct airflow to the radiator with ABS plastic which could be heated and shaped easily. In general the area of the opening in the bumper to a radiator should be about 1/3 of the surface area of the radiator as a general rule of thumb.
