Did you know, there is a extra lip on your driver's side intake duct?

Anythings possible. But the lip was put there for cigg butts and water mainly. Ive been fine with my smooth lip, and I think it looks better, lol. If I were you, Id consider doing a custom job. Buy those vents you like, then take a mold of them with silicone or alginate (prefer alginate) and fill it up with plaster. Return the vents you bought, get your money back, then take the mold to a shop and get them to fiberglass that plaster part for you. Then I would cut it to fit inside the stock intake and screw it in. You will probably have to get them to mold an inner lip so it still fits flush on the car. This way, you keep your stock lip, and you get that little ram air look you want. And you can also take it off and have it still look fine since the screw holes should be too deep in the vent to see. Maybe a crazy plan, but paying a shop $200 and making a mold yourself is cheaper than paying $400.
