BMC air filters are made of a multi-layered cotton fabric soaked in low-viscosity oil, inserted between two aluminium mesh frames. The aluminium mesh is coated with epoxy resin in order to protect it against oxidation caused by fuel vapours and the humidity present in the air. Impurities are filtered by means of sieving and retention processes, in other words the interception of impurities by the cotton fibres, which are then retained by the oil. The procedure takes place without obstructing the air flow passage, thus guaranteeing continuity of the air filter performance over time. BMC air filters are made using a procedure called “Full Moulding” that makes it possible to obtain the characteristic red filter from a single mould, with no gluingin the corners so as to prevent any breaking. The special rubber used in BMC’s filtration system is practically non-deformable over time and provides excellent adhesion to any air-box shape.

Generally speaking, vehicle such as automobiles or motorbikes require total particle filtration efficiency up to a minimum dimension of 10 micron, in order to avoid any risk of foreign bodies passing through large enough to damage the mechanical components downstream the intake system. OEM air filters are made of paper, and their main function is to protect the engine. These filters feature high resistance to the air flow which, consequently, reduces the pressure and the engine performance. BMC’s air filters allow the passage of a greater air flow. Moreover, compared to traditional paper filters which must be replaced when carrying out maintenance, BMC filters can be re-used so that they last as long as the vehicle itself.

BMC performance air filters are guaranteed against any production defect acknowledged by BMC SRL for a two years period starting from the date of the purchase by the final user at any BMC products dealer. Final users acknowledge that BMC filters can’t be commercialized by any dealer if more than 3 years have passed from the production date of the filter, since stocking filters for a period of time longer than 3 years might substantially alter the characteristics of the filter itself. BMC will therefore provide direct guarantee only if the purchase by the final customer occurs within three years from the production date of the filter specified on the Guarantee Certificate, where the production batch number is also stated.

No. However, to avoid any risk whatsoever, you have to be very careful not to use too much oil during the filter regeneration phase (it must not be so much that it starts to drip).

In order to maximise the benefits of the new air/petrol stoichiometric ratio and improve performance as much as possible, BMC recommends reprogramming the electronic control unit following the installation of an intake kit.

We recommend using original BMC kits only, as other products may not be effective or may damage the filter permanently, thus invalidating the warranty. The kit includes the special BMC detergent and an oil applicator (in the spray or dispenser version). We recommend regenerating the filter (washing + oil application) every 20.000 – 25.000 kms to ensure best performance and long service life. This value is a rough estimate and can vary based on the climatic conditions and the ground on which the vehicle is used (sand, dirt roads, etc.). The various steps to be carried out in order to regenerate the filtering element are indicated in the instructions contained in the regeneration kit
