CDA filtering system is composed of a cylindrical carbon air box containing a washable filtering element. Substituting the original air box with our CDA, cold air is directly channelled through an internal airflow deflector to the filter and drawn into the engine with a very small pressure drop (patented system). The CDA system also includes a black alloy ducting (60 cm length) for connecting the system to an air intake on the front of the car. The system is available in two different dimensions: we advise Type 1 for engines up to 1,600 cc; Type 2 for bigger displacements. Every type is also available in different diameters on engine side for connections. Dyno and Datron Laser tests demonstrate the great performance of CDA filtering system.
