Moroso Harley-Davidson Twin Cam (w/Stock Air Cleaner) Air Oil Separator - Polished

If you're looking to keep your Harley-Davidson Twin Cam engine running its best, especially with the stock air cleaner setup, an air oil separator is a smart addition. This unit from Moroso is designed to catch and separate oil mist from the crankcase vapors before they get recirculated back into your intake. This means cleaner oil in your engine, which can lead to better performance and longer engine life.

Moroso builds this separator with a polished aluminum finish, giving your engine bay a clean, custom look. It's designed to fit with the stock air cleaner assembly, making installation more straightforward. By effectively removing oil from the crankcase blow-by, it helps prevent carbon buildup and keeps your engine internals cleaner over time. This is a well-built component that addresses a common issue in high-performance V-twins.

Please note that this part is not CARB approved and cannot be shipped to California. It's also subject to California's Prop 65 warning. Always refer to the manufacturer's installation instructions for the most accurate fitment and setup details.
