Purolator B20009 Breather Filter sold2023 COMPATIBILITY Fits 2012-2017 Buick VeranoPurolator B20009 Breather Filter Breathers, also known as emission control filters, filter fresh air that's drawn into the engine's crankcase. Because the engine must breathe to purge itself of fuel and water vapors, breathers are used in conjunction with the PCV valve. Although small in size, Purolator breathers are big in importance. Like any other filter, the breather is used to trap harmful contaminants and prevent them from damaging the engine.
