The O.T.A - Oval Trumpet Air-box device is the new high performance air intake and filtration kit from BMC, designed and produced entirely in house and certified by the BMC Racing Division - Special Filters - that deal with the development of air filters for Racing: F1/MotoGP/WSBK/DTM/LE MANS SERIES/FIAGT.

This high level of know-how has enabled the creation of the new O.T.A device with first class records and results. The principal innovative characteristics are:

A) High filtration efficiency with reduction of load losses. Maximum passage of air with the guarantee of maximum retention of air impurities.

B) Elevated thermal isolation from heat sources of heat through a carbon air-box.

C) Oval air-box shape developed to allow high installation versatility of the device.

D) Oval Trumpet: A researched and developed internal formula for the channelling, carriage and increase of air through the introduction of the revolutionary system of air carriage called “Trumpet.” The “Trumpet”, placed inside the O.T.A device, on the air exit side, allows an increase in the quality of air introduced to the engine making use of the effects of dynamic carriage provided by its particular shape. This limits the loss of pressure along the air line of the engine, making the most of the dynamic pressure potential of the air produced by the speed of the vehicle in movement.

E) The air-box fitting system ensures maximum sealing of its components, guaranteeing the maintenance of device pressure at all times. This translates, in consequence, to an increase in torque (NM;) and engine horsepower (HP) across the entire arc of engine use.
