These scoops force air to go the opposite direction, creating turbulence and reducing proper airflow over the car. So, in effect, they do nothing worthwhile and simply impede performance.
If anyone has any info contrary to this I'd be most interested in hearing it.

I'm not sure about the Do-Luck scoops but...
On the Toms MR2 they designed the Toms scoop to connect to their induction box for the N/A to act as a ram air effect, but in order for it to work you need the toms air box which is as rare as rocking horse poo and i've only seen a couple of photos of them on a few cars in the UK, they only produced the left hand side (near side, passenger side on a jdm/ RHD mr2)
the offside toms scoop is just a replica and they never produced it,
they never ment them to aid in any type of cooling except for ram air.
I'm not sure about the border or du-luck ones,
