Parts 13 and 14 are not on the car. Where the grill (P14) attaches there are no holes.
It looks like BMW ditched these because the Light assemblies impede on the elbow some.
I cut away where the holes should be after looking a nearby M3. Then made my own elbows out of old plastic containers. I finished it all off with Blk duct tape to create a closed intake.
There are also holes on the outboard side of each Part 11. I was able to close those up thus getting cold air from the front grill only.
With my AK Motion reading IAT's I went from 20-25 degrees over outside air temp to 10-15 over at any decent speeds. Even less at 75+ MPH
If all the M2C's are the same then your sucking in hot air from the engine compartment.

Thanks for pointing this out, I just checked my car and I was also surprised to see that there are no air inlets behind the kidney grills as well!!
I analyzed the front bumper thoroughly and it seems the intake sucks air from narrow inlets perpendicular to the oil cooler.
Now I understand why you cut holes behind the kidney grills, I wonder why BMW ditched the inlet elbows on the M2c.
Did you try fitting the M4 elbows? Can you please share some pix of how you did this??
I took a pic inside my grill to make it clearer for everyone and check out the M4 intake elbows from realoem..
Cheers
