Product Details
If you're working on your 2020-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, this K&N Air Oil Separator is a smart addition to help keep your engine clean. Over time, your engine can produce 'blowby' – gases and oil vapor that escape past the piston rings. This separator captures that oil before it can get back into your intake system, which helps prevent power loss and potential engine damage.
This unit replaces the factory line from the crankcase and is designed to mount in a convenient spot in your engine bay. Installation is straightforward, usually taking about 30 minutes with basic tools, and it uses factory-style hose connections that snap right on. The high-capacity reservoir makes it easy to check and empty, and no special tools are needed for maintenance. K&N backs this with their No-Hassle Lifetime Limited Warranty.
