Here's some pics of the WS-6 Ram Air hood in its current state as of the day of this posting. Due to change without notice.
The hood has open vents in the front and back but the underside is not open by default. You can easily make the cooling functional by opening the holes on the inside of the fiberglass Duraflex WS6 hood with a dremel tool or air powered grinder.
Carbon fiber looks pretty good on yellow cars with black accents, so why not put the Carbon Creations CV8-Z hood on and find out. It looks like this owner did just that and the result is pretty good. The contrast of the carbon fiber suits the car nicely, it flows well with the kidney grille, fog lights and central front bumper duct. It's a shame they stopped making the GTO. One of the few Pontiac GTO Carbon Fiber Hoods available for this car.
Here's some pictures of the raw hood, it's the Duraflex CV8-Z style for the Pontiac GTO. You can see the functional ram-air vents and the underside of the hood in these pictures.
Here's some pics we took of the hood. As you can see the Spyder 3 Duraflex Fiberglass does not have a cut-out for the ram air duct, but the indent can easily be dremeled out to become a fully functional hood.
Here's some measurements and photos of the underside! As you can see the scoops are not pre-cut, but can be opened up to be functional.
