BMC Oval Trumpet Airbox - universal till 1600cc

This BMC OTA dynamic intake kit, designed for engines up to 1600cc, with an air inlet diameter of 70mm and including two reducers in 60 and 65mm, is a complete solution for engine air intake and filtration. It consists mainly of an oval-shaped carbon fiber airbox containing a cylindrical air filter with a dynamic inlet. Unlike the original airboxes that operate in a depression regime with reduced-section tubes, the OTA system works in a pressure regime, ensuring a constant and high air flow to the engine through the dynamic effect of air pressure.

Its innovative element, trumpet-shaped and strategically located near the air outlet, promotes optimal transfer of the airflow to the engine, reducing turbulence. This intelligent solution minimizes pressure drop along the engine's intake line, harnessing the potential of dynamic air pressure generated by the vehicle's speed in motion.

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.
