The top one and 3rd one are both functional hoods,just depends on what you want out of it.
The top one is Ram Air, have to purchase the Kit if you want it fully functional,

The 3rd in a heat extractor style hood- supposed to keep engine bay cooler.

You should buy it through stage3 so you can look at it before you purchase to make sure there are no flaws.
They usually cary more then one.
