The link just shows K&N watershields, which are "hats" that sit on top of the filters to keep rain out of them.
The phrase you're using sounds like a "breather box". Search for that term on here and you'll find a lot of results... It's intended to keep the oil vapor from the heads and oil filler from spraying all over the engine bay.
