These baffled breather grommets virtually eliminate oil blow-by, a common problem on non-baffled valve covers with push-in breathers, by letting only vapor exit through the breather. They replace the stock grommets in 1-1/4 in. valve cover holes and install with no tools. They are for valve covers and rocker arms without stud girdles.
