What's Unique About Our Crankcase Breather?
A CFM Performance crankcase ventilation breather, more simply known as a "crankcase breather", is a direct replacement for the factory oil cap on your valve cover. It allows unwanted positive pressure to be released from the engine's crankcase, yet it remains sealed under a vacuum. This prevents air from entering the system (causing a lean condition), which is a very common problem with many aftermarket breathers. It is also the only breather with a baffle to keep oil particles from saturating the filter.Now available for Dodge/Chrysler/Jeep, GM and Ford applications!
