The panel / cylindrical air filter is commonly referred to as "replacement air filter". It is installed in the vehicle's original airbox to replace the OEM air filter. It is made of highly performing materials that allow an increased air flow combined with a more efficient filtration, guaranteeing containment of all impurities from as small as 7 microns (compared to OEM's 10 microns).

This chart has a pure illustrative purpose and does not refer to the present filter.

BMC air filters are produced using a "Full Moulding" system that enables the characteristic red filter to be realized from a single mould with no welded joints thus avoiding easy breakage. The rubber used in BMC air filtering systems has a long life, is very durable and has optimum adhesion characteristics to all shapes of airboxes.

BMC filters are made of a multi-layered cotton gauze soaked with low viscosity oil covered with an epoxy coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity.

All BMC air filters are pre-oiled, and they can be washed and regenerated by using the appropriate BMC regeneration kit.

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).

Schema OTA

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 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, 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.

The air filter inside the air box 1 is made of a multi layer pre-oiled filtering material which grants an 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 air flow to the engine during the aspiration phase. BMC air filter has a very low drop (i.e. the pressure difference between the air flow at the engine side and the one at the air entrance side) in order to enable the maximum air flow.

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