What is it?

The m3/m4 elbow joint will fit. It snaps in to the intake snorkel and then you need to cut the plastic trim so it has an opening for the cold air. That is an option.
The question I had was whether a piece could be made that does not require a 90 degree turn of the airflow - which while definitely better than stock ( which is closed off) - maybe less than optimal in terms of flow velocity, volume, and turbulence.
So I've been crafting a new 3D printed piece that fits into the stock intake snorkel and then allows a straighter path to clean air. Below are some of the mock ups I used just to test the measurements and the interface. It is NOT the actual design of the snorkel.
There are additional questions here: the stock BMW piece is narrowed already (see the picture) - does this matter? Unclear.
Will there be any difference in air flow between more of a ram air scoop and the stock m3/m4 piece? Unclear. My guess is that at slow speeds they would be the same and at higher speeds the ram air would push more air in... again it remains to be tested.
My plans include IAT comparisons and then we will dyno before and after with the biggest fans we can find. Then of course, we will get some track laps.
If nothing else, its been a fun project during these crazy times at home.
