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).

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.

BMC started in 1973 as an automotive parts distribution company, and they began developing filters in 1996. Today, BMC air filters is one of the best known automotive air filter companies in the world. They started in Bologna, Italy, but now they have offices all over the world including Germany, China, and India.

In 2010 BMC Air Filters began developing composite materials for use with their air filters. These advanced composites materials are used to develop airboxes for BMC air intake systems. BMC achieved certifications EN 9100 : 2018 and ISO 9001 : 2015 for the design and manufacturing of air filters and composite materials for aerospace, automotive, naval and industrial sector.

Why Replace Your Air Filter?

You might be wondering why you even need to replace your air filter. As the name suggests, air filters are designed to filter the air being sucked into your engine. Without filtering the air particles will be sucked into the engine and cause internal damage over an extended period.

Automotive manufacturers must build their vehicles to a cost, which means some parts are less than ideal in engineering and quality. In general, OEM filters are typically made of paper and heavily restrict airflow and can't be replaced, and they offer limited filtration properties in many applications.

By replacing your air filter with a cotton air filter, like the ones offered by BMC, you can improve filtration and airflow significantly. Many aftermarket filters, including BMC air filters, are made from cotton which offers better flow and filtration characteristics compared to an OEM filter.

Why Choose BMC Air Filters?

There are lots of options for aftermarket air filters, so why should you choose BMC air filters? With a big focus on quality, air flow, filtration, and longevity, BMC is one of the best options on the market.

  • BMC air filter guarantees containment of impurities as small as 7 microns
  • They build their filters from natural cotton and they can be washed, re-oiled, and reused.
  • BMC carries out filtration testing in reference to International Standards for filtering (ISO 5011)
  • A BMC air filter will last for the lifetime of most applications
  • BMC is used by some of the most important race teams in Formula 1, Le Mans, Moto GP and World Superbike
