Not wanting to rain on anybodys parade here, but....

I dont know why you want them open?? unless you have Ram Air set up...
well, it "looks" real..but with black paint vs. the real opening, you eliminate a couple of problems...

1) bugs
2) dust
3) rain,....which I think would be the worst..think about it..it rains it goes in there..its not like when it hit radiator and disperses on a hot engine, and evaporates..
up by the scoops , you have 2 situations , one, if you have the insulation ,it will stay moist up there, cause rust..
two, if you dont have insulation , moisture will blow in under the braces on the top of the hood, and into the back corners , and "maybe" evaporate if its really hot up there , but if its not ,you`ll have water or moisture up under those braces and it will eventually rust...

actually ,in my case I went the other direction, I didnt like the small amouts of water coing in around the scoops ,that wont seal 100%, even at washing the car, so I sealed the scoops to the hood with silicone (that you cannot see)after paint, so nothing gets by...esp, since I have the hood insulation ,and dont want any moisture under there...( I may have problems anyway ,since I bought a used hood that had surface rust ,and I couldnt remove all of it under the braces or in corners ( I sprayed in TecWax, but not sure it would get everywhere)....I expect that to bubble up after a few years)
