Admission dynamique OTA BMC univ. waterproof plus de 1600cc

This is a complete kit for engine air intake and filtration. It consists mainly of an oval carbon fibre air box containing a cylindrical air filter with dynamic inlet. The OTA kit completely replaces the car's stock air-box.

"WP' stands for 'Waterproof', the new OTA line, specially designed for off-road conditions and harsh environments (water, desert).

Normally, stock air-boxes work in these conditions, because the air is drawn back by the engine in 'negative pressure', through tubes of reduced cross-section, resulting in a sharp drop in charge along the intake line. The OTA device, with its dynamic inlet, operates in 'pressure mode' and therefore supplies a constant, high quantity of air to the engine, taking advantage of the dynamic effect of air pressure.

In addition to its oval shape, which offers great flexibility of installation, the OTA system introduces technical solutions on the inside that optimise fluid dynamics from the air to the engine. In particular, the innovative "TRUMPET" element, located inside the airbox in the area close to the air outlet, thanks to its shape, favours and optimises the transport of the air flow towards the engine, resulting in reduced turbulence. This solution reduces the pressure drop along the engine intake line and, at the same time, takes advantage of the potential for dynamic air pressure caused by the speed of the moving car.

The air filter inside airbox 1 is made of a pre-oiled multi-layer filter material that guarantees high filtration efficiency against a limited pressure drop in the air. The function of the air filter is to protect the engine from all elements (debris, sand, dust, etc.) present in the air flow to the engine during the intake phase. The BMC air filter has a very low pressure drop (i.e. the difference in pressure between the air flow on the engine side and that on the air inta
