Thanks to the experience gained by BMC in creating supercharging dynamic airboxes, BMC developed the Direct Intake Airsystem (DIA), the "junior" filtration system.

The philosophy of BMC's top range product, the Oval Trumpet Airbox (OTA) is behind the DIA, a system that, with its particular structure, ensures that aspirated air is carried to the engine at a higher speed and capacity in respect to traditional systems, thus providing significant gains in engine performance. 

The DIA consists of a plastic airbox containing an air flow deflector and a reusable air filter.
