I don't recall this being discussed before (although I'm sure it has been at some point). This falls under the "customized X" category, so if you are a purist then you might go to the next thread now. I've been considering a custom "large intake duct" modification for the side vents (that feed cool air to the engine bay). The motivation is two fold; 1) I think it would look good, to me the stock ducts seem too small proportionately for the car; and 2) Hopefully they would bring more cool air into the hot engine compartment. I guess now would be a good time to mention that I don't have anything connected to the stock ducts on the inside (none of the blowers, hoses, etc). So the ducts just serve to direct air into the general bay area as the car is driving. There are a few directions (style wise) this could go: Larger 'scoops' over the existing openings, replacing the stock 'boxes'. This is sort of along the lines of what FAZA did as part of the Abarth Stradale package, but I'm thinking more like this example from the MR2: Bigger openings with 'grills'. Maybe something like some early Porsche Turbo's had: Or on the Miura: Although I think the X's body is too small for the full "Testarossa" look. I believe it was the Eurosport body kit that tried a version of this?: I like several of the 'vintage Italian sports car' styles: Has anyone built something along these lines?
