aFe POWER Crank Case Breathers

The smallest of aFe's Performance Racing Filters are the Crankcase Vent Breathers. These filters range in size from a 0.31-inch to 1.5-inch flange ID. The filters’ height ranges from 1.13-inch to 3-inch. Since these are generally used right up against the crankcase, some of these breathers have a chrome shield to protect the filter from the heat.
