These filters have high resistance to the air flow, which reduces the inlet pressure and reduces the engines performance. BMCs air filters provide a considerably greater amount of air flow. 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 breakage.
