Breather Filter 10 mm Flange 2 in OD 1-3/4 in H Stainless Steel 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 version uses stainless-steel mesh and comes pre-oiled from Spectre. Its compact clamp-on format makes it useful for custom crankcase, transmission or differential vent applications that match the listed flange size.
