I understand the issue is that the grills restrict airflow to the radiators (which they must), and that can lead to all sorts of problems- allegedly
Before I fitted the grilles I had asked another OPC service dept, who said it was a great idea, wouldn't affect airflow or warranty, and they wished Porsche would fit them as original equipment. I checked with OPC Leicester who said no problem, so I later fitted the grilles, took the car in for the extended warranty to be applied, no issues whatsoever at that point in 2017.
I'd gone to the first OPC with a leaf stuck in the side intake which was creating a machine gun noise as the fan attacked it. They retrieved the leaf and so I fitted the side grilles too.
After all the grilles were fitted I passed a lumber truck on the motorway. A lump of tree fell off, some of it bumped under my 981, and when home a wood stake around 5" long was stuck point first in a front air intake grille. I pulled it out, no damage done to the car or grille.
After all that, both condensers failed, one in in 2019, the other in 2023.
Here's one of the rads before the grilles were fitted at around 15k miles...
