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.
Best,..

Good work Hazmat - UK B58 mx40i owners found similar issue - work around was to retrofit B58 "hot climate" spec elbow and grill parts...
