My new Seat Leon Cupra R 2018 310 have the whole cover/engine shield (OEM mounted) with the two gearbox vents, 3Q0 825 236 C.
My former Golf 7 R had the half cover, 3Q0 825 235 A.
The Cupra R have a rather big front CF splitter which presses in much air via lower grill into the engine bay, therefore I’m considering to open up say 4x 30mm round holes to help the air to evacuate in the rear part of the under shield nearby the sub frame since it's a "whole cover".
I also checked the German forum tread below about airflow running through the engine bay.
(Good opportunity to practice “Deutsch” )

FYI The people in the tread says there is pressure from under the engine which slightly hinder the airflow to go through the engine bay. This phoneme is prevented with the help of a whole cover 3Q0 825 236 C. This means the whole cover increases the airflow instead of the opposite way around.
What do you think about drilling holes in the rear of cover? Perhaps just a waist of time. I have no issues with it, have hardly used the new Cupra yet but in time I will go to the track with it.
