This is an oil separator catch can, not a filter. The K&N 81-0812 intercepts oil vapour from the crankcase ventilation system before it reaches the intake, collecting it in a serviceable reservoir instead of letting it coat the intake tract.
Key Features
- Separates oil vapour from crankcase ventilation gases
- Collects oil in a reservoir that is emptied at service intervals
- Helps keep the intake tract and intercooler free of oil film
- Vehicle-specific mounting
Fitment
2020-2025 Chevrolet Silverado 2500HD and 3500HD and GMC Sierra 2500HD and 3500HD, 6.6L Duramax V8 diesel.
