The Harley-Davidson M-8 High Performance Engine Breather is a specialized billet cam cover, expertly crafted by Vance & Hines Motorsports, designed specifically for high-performance racing M8 engines. This includes engines like the SE 131 crate engines and SE stage IV kit builds, particularly those with large cam profiles. Its primary function is to reduce crankcase pressure, enhancing the engine’s overall performance and durability. This is achieved through an innovative oil separation mechanism using a centrifugal breather, which ensures superior engine oil containment. An integral part of this design is the built-in reed valve system, seamlessly integrated into the cam cover. This system is engineered to use the stock cam drive system, ensuring ease of installation and compatibility. However, it’s important to note that this product is not compatible with VVT Models, limiting its use to specific engine types. This makes it an essential component for racing enthusiasts and professionals looking to optimize their M-8 engine’s performance.
