The most revealing signs of a carburetor company's standing are its reputation for innovation, its record of success, and how easy it is to deal with. When the Demon range of four-barrel modular carburetors first burst onto the scene in the late 1990's, it acquired a meteoric reputation for innovation. Immediately noticeable was its uniquely attractive appearance with beautifully contoured air entries and shapely fuel bowls. This coupled with its vast array of ground-breaking features set it apart from the competition.
