What are Breathers?
Breathers are the other half of a crankcase emission system. A breather filter cleans the air that is drawn to the crankcase and later let out by the PCV valve.
Breathers act as an inlet to your vehicle’s crankcase. They help prevent contaminants from entering the air filter.
Breathers are the other half of a crankcase emission system. A breather filter cleans the air that is drawn to the crankcase and later let out by the PCV valve.
Breather filters usually are contained in a slot or small box that connects to the air box then to crankcase. They clean the air that travels through it.
Most breathers are a block or square of media material that is cut or formed.
