Also adding more heat to the combustion process will increase NOx.

Yes, but your/my 6.5L doesn't have an IAT sensor like my wifes CR does.
Things get all wibbly wobbly when the ECU decides to help the engine warm up by messing with the injection timing/duration.
Simply adding a resistor to the IAT doesn't work as the computer sees the change at the O2 sensor (yes there is one) and tries to compensate.
I disconnected the snorkel on the CR...... and the next day the temp outside went from 40° to 65°.
We have a 2+ hour trip this weekend. Friday evening will be 60s, Sunday will be 45°.
I will let yall know what happens..........
