Filtre à air BMC Race - FM114/04RACE Honda

Sizes (mm): B : 104 | A : 280 BMC RACE filter range Keeping the same shape as the OEM version, with BMC Race filters the increased airflow typical of BMC products is taken to a more extreme level. By reducing the cotton layers from 4 to 3, the air delivery is even higher. For this reason, BMC Race filters are only recommended for sports use on the racetrack, as the increased air flow can lead to poor carburation (more air than necessary) or injection (the control unit is unable to control the stoichiometric mixture correctly). To avoid this problem, it is necessary to reprogram the control unit, which results in a marked increase in performance.For easy identification, BMC Race filters have the word "Race" written at the end of the product code and a yellow line on the filter element. Why choose a BMC air filter? 1. Better air flow to the engine:The cotton gauze BMC uses has larger links, allowing a better air flow, but using several layers of oil soaked cotton allows to block any impurity larger than 7 microns.2. Greater retention and screening:BMC air filters scored an impressive 97,5% filtration efficiency at ISO5011 test.3. Wider filtering area:Maximum air permeability and higher air flow passage.4. The choice of champions:BMC equips some of the most important team in Formula 1, MotoGP, WorldSBK. General information 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).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. Air flow chart for a sample BMC air filter against an OEM paper filter  Temperature 25C° - Humidity 25% - Pressure 1020mbar.Test ran with oem airbox, and the related air flow constrictions.This chart has a pure illustrative purpose and does not refer to the present filter. How to clean your filter?
