Oil Breather Cap Breather Push-In 3/4 in W/Grommet 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.
This breather-style component is intended to provide controlled crankcase or valve-cover venting in a compact push-in or twist-in format. Match the listed opening, grommet and tube arrangement to the engine before installation.
