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

In addition to its oval shape, offering high installation versatility, OTA system introduces in its inner part technical solutions which 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 air flow 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.
