High-Performance Breather. The CFM Performance Baffled Billet Valve Cover Breather for Holley Cast Aluminum Valve Covers in Chrome is engineered to efficiently vent crankcase pressure while preventing unmetered air intake under vacuum conditions. This billet breather replaces the factory oil fill cap to ensure proper crankcase ventilation, which is essential for maintaining engine performance and longevity, especially in high-demand driving or racing environments.

Construction and Appearance. Crafted from high-quality billet aluminum with a chrome finish, this breather combines robust durability with a polished look. It features a proprietary internal baffle and a washable, pre-oiled cotton fiber filter element designed to trap oil particles and dirt without restricting airflow, enhancing both function and visual appeal under the hood.

Installation. Installation is straightforward as it directly replaces the factory oil fill cap without the need for drilling or modifications. This product is designed for ease of fitment, making it accessible for both professional mechanics and experienced enthusiasts.

Application. This valve cover breather fits 1997-2013 Corvette C5 and C6 models but excludes the ZR1 variant due to specific valve cover differences.
