It appears to be a corner scoop, yet vented like an "air curtain" to perhaps prevent excessive pressure build up while turning into corners.

Yes, the Fast & Furious Supra uses the Bomex front bumper.
Is usually the zone in front of the front wheel a low pressure one or not?

Thanks

What does the research I suggested you do reveal?

Please post your results.

Note: I think you are on the right track in not assuming all vehicle front ends are pressurized exactly the same.

Porsche moves the radiators to the front for airflow and car balance, if I had a Free Hand in this case I'd try the Porsche plan. Put NACA ducts in front of the rear wheels, move the radiators there and vent the air into the Low Pressure area at the center rear of the car. Then fill in and round the openings at the front. For low drag, the best are always "Smoooooth".

Why would you want to slam air into a vent only to slam it into the front of your rotating tire? That makes absolutly no sense.

Where is the air vent in the above photo? Why would you do it if Nascar is not?

It's a Porsche thing, on the water cooled 911's it's radiators, and on the air-cooled / oil/cooled 911's it's oil coolers dumping hot air on to the tires.

They build long lived cars and have won more races than any other make, must be doing something right, right?

I'm not sure we want to get into why a 200 mph race car is different and compare it to a street car which might get stuck in traffic.

That's a big subject.

Appears to be a wheel well liner.

^ I know this. I am talking about why the OP wants to redirect the air to his tires for no reason. He stated he will not be using it for any reason other than "attempting" to move it to a lower pressure area or trying to make a nice looking air vent that would actually do more harm than good for his aero.

At stated previously his best bet would be if he just smoothed and closed that area since he already stated:

I already catch the air for brakes with 2 duct beside the central intercooler

PS: engine bay is separate from these vanes
Thank you.

I don't know why he wants to move anything, but your deduction may be true.

Still waiting to hear why he "needs" to move anything.

There is a difference between "need" and "want", maybe he meant "want"?

Now the question is why the OP needs to increase the oil cooler size.

Thanks Jeff, I missed that somehow.

Maybe he added a turbo?

I looked it up, found this:
Cooling Components - 1993-98 Supra

Your stock oil cooler is a joke...its a tiny water-cooled device sandwiched between the oil filter and engine block.

I think most people just put aftermarket oil coolers in front of the stock radiator.

Oil Cooler Design Basics | How to add an oil cooler to a car

The best place to install an Oil Cooler is where it can receive a maximum amount of airflow, there by making the cooler as efficient as it can be.

So it already looks like the above image?

Don't the aftermarket ones have more fins and are more efficient?

First of all, thanks all for your interest.
Seems that I need to add some informations.

I'm an engine builder and an efi ecu mapper.
My car is originally turbo, but later it was upgraded (power, cooling, etc) for mountain roads races.
From the logs during races, I see that oil temp has a wide range, that I'd like to narrow to activate specific ecu strategies.
And to reduce the temps' range, I absolutely need a bigger oil cooler.
Only place in front of the car to fit a bigger oil cooler is that vane under the headlight, but, obviously, i'm going to fit it there only if it's going to work well there... that is to say if i'm going to get good air pressure to feed it and low pressure behind it.
Thanks
