I went with a very simple design. I used the same vent placement as the MTM vents (with smaller side vents). I found a mesh with the same shape/size as the front grill, painted them matte black and coated for protection. All the cuts were done with a dremel, and most of the time was buffing, grinding and filing the edges down to get them smooth and rounded. Paint was done at a certified Audi/Ferrari body shop.
Now to what matters - The average oil temp for my one hour drive to work went from 225 f to 200 f. When stopped, i can visually see the heat pouring out of the hood like an oven. Also, when i get the car in the garage, the hood cooled to the touch 2 hours faster than before. It may be a simple design, but it pulls quite a bit of heat out of the engine bay while driving and while stopped. i am very happy. Thank you Headshot for the inspiration/guidance.
