We used to see a lot of that with "Ram Air" systems in the muscle car era when people were we just starting to learn about how aerodynamics effected air flow into the induction system. Lots of cars like my Tri-Power Ram Air GTO got it wrong (but the CAI part was right) while the 442 ram air with scoops under the front bumper & big block Chevelles' with cowl induction got it right both from a ram air & a CAI approach.
Lots of this stuff was all about styling so many muscle cars with intakes in the middle of the hood got it wrong unless they were pretty tall & got out of the boundary layer.
EDIT: For a mid hood scoop that actually worked look at Sox & Martins' HEMI race car.
