The fog-light and surround blocks the air-flow. In the original FR bumper there are air-intakes at the same location as the SMIC is directly behind it.
If you open the bonnet you should be able to see the SMIC away in the corner.
I ran mine for a while with the fog-light out but it looked terrible!
Also the left part of the grill on the
Cupra bumper is solid whereas the rest is mesh, think this is because of the towing eye cover but seems silly. I know someone on here drilled the solid bits out but not something i would start to do.
I never took my bumper off myself so im not sure whats behind it and if theres another way to direct airflow to the SMIC. I searched this before and only answer seems to be replacing SMIC with a FMIC.
The new face-lift FR bumper would probably be a better bet....
