DEI Cryogenic Air Intake 4in I.D. - 4 1/2in O.D.

The CryO2 patented* Air Intake consists of an aerodynamically designed bulb with a cryogenic chamber which is mounted in a short segment of air tube. Air is cooled as it passes over the bulb, resulting in a cooler, denser, more powerful intake air charge. Testing showed up to a 50°F reduction in intake air temperature.
