BMC Oval Trumpet Airbox - ACOTA70/85L170-B-WP

BMC Oval Trumpet Airbox - ACOTA70/85L170-B-WP

It is a complete kit for engine air aspiration and filtration. This device is mainly composed of an oval-shaped air box in carbon fiber containing a cylindrical air filter with a dynamic inlet. OTA kit replaces the original car filtration box (stock air box).

"WP" stays for Waterproof, the new OTA line, specifically designed for heavy off-road conditions and hard environments (water, desert).

Usually, the original car airboxes work in such a condition as the air is recalled by the engine in a "depression regime", through reduced section tubes, thus resulting in a high load drop along the aspiration line. The OTA device with its dynamic inlet works in a "pressure regime", therefore it provides a constant and high-rated quantity of air to the engine taking advantage of the dynamic effect of the air pressure.

In addition to its oval shape, offering high installation versatility, the OTA system introduces in its inner part technical solutions that optimize the fluid dynamic of the air to the engine. In particular, the innovative element called "TRUMPET", which is situated inside the air box in the area close to the air outlet, thanks to its shape, favors and optimizes the convey of the airflow to the engine, resulting in the diminishing of turbulences. This solution reduces the pressure drop along the engine aspiration line and, at the same time, takes advantage of the potentiality of the dynamic pressure of the air caused by the speed of the moving car.

The air filter inside air box 1 is made of a multi-layer pre-oiled filtering material which grants a high filtration efficiency against limited pressure drop in the air. The air filter has the function of protecting the engine from all the elements (debris, sand, dust, etc…) in the airflow to the engine during the aspiration phase. BMC air filter has a very low drop (i.e. the pressure difference between the airflow at the engine side and the one at the air entrance side) to enable maximum airflow.

BMC air filters can be regenerated and reused. Once the saturation level has been reached, it is possible to
regenerate the filter by washing and re-oil operation performed using the relevant regeneration kit.
