Breather Filter Push-In Extraflow Blue is a crankcase/vent breather designed to filter air moving through compatible valve-cover or vent plumbing. Breathers matter because crankcase and vent systems still need airflow, but leaving a tube or valve-cover opening exposed can allow dirt and debris to enter the system.
Spectre performance breather filters commonly use pre-dyed synthetic media in a compact clamp-on or push-in design. The filter-style construction adds useful vent filtration while giving the engine bay a finished performance look.
