BMC Oval Trumpet Airbox - universal from 1600cc

This BMC OTA Dynamic Air Intake Kit, designed for engines over 1600cc, with an air intake diameter of 85mm and includes a reducer of 70mm, is a complete solution for engine air aspiration and filtration. It mainly consists of an oval-shaped carbon fiber airbox containing a cylindrical air filter with a dynamic inlet. In contrast to the original airboxes that operate in a depression regime with reduced section tubes, the OTA box operates in a pressure regime, ensuring a constant and high airflow to the engine through the dynamic effect of air pressure.

Its innovative trumpet-shaped element, strategically located near the air outlet, promotes optimal transfer of the airflow to the engine by reducing turbulence. This smart solution minimizes pressure drop along the engine's aspiration line, leveraging the potential of dynamic pressure generated by the speed of the moving vehicle.

The air filter inside the airbox is made of a multi-layer pre-oiled filtering material, ensuring high filtration efficiency while maintaining a limited pressure drop in the air.
