Metco Valve Cover Breather For 98-02 LS1 Camaro/Firebird MBR0003
Crankcase pressure has long been considered detrimental to engine performance and gasket sealing. As pressures increase through performance and age gaskets often begin to leak. By venting the crankcase to atmosphere those pressures are greatly reduced. Metco valve cover breathers are CNC machined and polished to a show quality luster. The filters are washable with soap and water and fit OEM valve covers with no modification.
