BMC Air Filters are designed and produced to ensure a higher air flow than original paper filters. In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. 

BMC panel filters just replace the original filters in the filter box. They are filters that replace original paper filters in the filter box. Air filters replacing original BMC ones are designed and made to guarantee greater air capacity than traditional paper ones. BMC filters use aluminium net treated with epoxy resin to guarantee resistance to fuel vapors and oxidising due to humidity. The filtering material is special cotton soaked in low viscosity oil to guarantee greater permeability to air.
