K&N 20-23 GM 2500/3500 6.6L Oil Separator Catch Can

The K&N Air Oil Separator protects the engine and intake tract from blowby by capturing the oil in our industry leading high capacity reservoir. This helps prevent power loss and possible engine damage caused by blowby. The K&N Air Oil Separator is quick and easy to install in about 30 minutes with basic tools and uses factory-style hose connections to quickly snap on and off. The oil separator replaces the factory line from the crank case allowing the oil separator to be mounted to a coinvent location in your engine bay. No tools are needed to check and empty the oil collector reservoir. Each unit is engineered specifically for your vehicle and is backed by our No-Hassle Lifetime Limited Warranty.
