2 doors about 2X2 on each side of radiator cover
Can anyone tell me what those 2 doors about 2X2 on each side of upper radiator cover do? Mine flap open with my fingers.

The total is 3. The drivers side has 2. One right above the other.

Looks like they open at speed. Not spring loaded or anything like that.

Additional cooling for the radiator at speed, when the fan kicks on it sucks them closed for the fan to function effectively.

Pretty much every car has those. The faster you go the more they get pushed open to increase passive cooling versus baffling the fan in traffic.

Interesting. No springs or anything. Just a flap?

NASCAR inspired! Like roof flaps.
