I will post pics of my rear engine In the next 6 weeks as soon as we get the patent for the tuned cold air injection Airbox. Which fits with almost any rear deck tail. Here's a pic with the GT3RS rear. I have added the tail light since the pic.

I have this supercharger kit,just like the vf and I want somehow to increase the cooling at the engine bay
Mines is cabriolet and it's difficult to find something

It is true that the top picture of the 997.2 GT3 has ducts, but not for cooling of the engine. If you look at your engine compartment, the location of the bumper ducts is not in direct path with the engine compartment. When I was looking at this bumper as a potential modification for my 997S with the VF S/C, I contacted GT3Tek, and they mentioned that the ducts are for aerodynamic purposes, and not for cooling.

I have to look at my car when I get home, but on the 997.2 GT3, the upper vent near the decklid are just cosmetic. Does not vent into engine compartment. Those vents are wire mesh with a plastic bracket to hold them in. Behind it is the upper bumper bracket connected to the tub/frame/chassis, whatever you call it.
