Any CAIs will work. You just have to either make a bracket to rotate/move the coolant overflow reservoir, relocate the reservoir, or custom the intake pipe so that they don't obstruct with one another. 


If you just want to turn off the V4 mode and auto start/stop, then the range is all you need. If you want anything beyond that then a tune is best. I only know of BBP that has tuned eAssists. It's not supported by the others.
