The K&N Oil Separator Catch Can fits the 2020-2025 Chevy Silverado 3500HD 6.6L and protects the engine and intake tract from blowby oil.
Product Overview
This air oil separator captures blowby oil in a high-capacity reservoir before it reaches your intake tract. That prevents intake fouling, power loss, and long-term engine damage on the 6.6L.
It replaces the factory crankcase line and mounts in a convenient engine bay location. Factory-style hose connections snap on and off, and the reservoir empties by hand with no tools.
