The silver part is the airflow deflector...

You suggest to remove it?
Just one observation, you shouldn't block the hotend fan (small fan behind you have block the airflow, the part in front of the tfm coupler with your fancap should be open), you are blocking the heatsink effect with your fancap, than can cut drastically the life span of the coupler.
Also, by allowing to have more heat onthat zone, filament can expand and make much more difficult for the feeder to keep up. That would explain why the underextrusion effect shows more on areas where your print needs retraction.
