BMC Direct Intake Air system (universal)

About the DIA - Direct Intake Airsystem

Thanks to the matured experience of BMC in the supercharging dynamic air boxes, they have developed the Direct Intake Airsystem (DIA), the junior filtration system by BMC.

The philosophy of the BMC top range product, the Carbon Dynamic Airbox (CDA) is newly proposed in the DIA, a system with its particular structure, ensures that the aspirated air is carried to the engine at a speed and capacity superior respect of traditional systems, with a significant gain to engine performance. The DIA consists in a plastic air box containing an air flow deflector and a reusable filtering element. The universal kit also contains a flexible tube to carry fresh cool air to inside the air box, a connector sleeve and two reducers to allow the installation in more popular applications.

The universal DIA (models DIA70-130 and DIA85-150) are effectively the same in basic overall geometry and functionality as there universal CDA counterparts (CDA70-130 and CDA85-150). The only major difference is the use of plastic as the main casing material instead of carbon fibre.

By avoiding the use of exotic materials in its construction, the DIA brings the incredible patented high performance technology of its bigger brother the CDA in to one amazing value package!

DIA Technical Information

The DIA filtering system is composed of a cylindrical plastic air box containing a washable filtering element. Substituting the original air box with the DIA, 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 DIA 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 (DIA70-130) for engines up to 1,600 cc; Type 2 (DIA85-150) for bigger displacements. Dyno and Datron Laser tests demonstrate the great performance of the DIA filtering system.

The DIA air box was developed by BMC primarily as a universal application and can be adapted to fit most vehicles. In many cases accessories may be required to fit a DIA system to your vehicle. Type 1 & Type 2 Universal versions of the CDA are supplied with the following accessories as standard:

Type 1 (DIA70-130) - 70mm OD (Outer Diameter) standard neck outlet plus 2 x nylon connectors to reduce to 65 or 60mm OD necks. Also includes a detachable cold air feed kit, metal bracket to secure the filter within your engine bay and installation instructions.

Type 2 (DIA85-150) - 85mm OD (Outer Diameter) standard neck outlet 1 x nylon reducer to 70mm OD neck. Also includes a detachable cold air feed kit, metal bracket to secure the filter within your engine bay and installation instructions.
