Moroso 85533 Air/Oil Separator Catch Can for 2014-2019 GM Trucks

The Moroso 85533 Air/Oil Separator Catch Can is engineered to protect your GM truck's engine by removing oil vapor and contaminants from the crankcase ventilation system before they can re-enter the intake tract. This large-body catch can features a high-capacity design that efficiently separates oil mist from blow-by gases, preventing carbon buildup on intake valves and maintaining optimal engine performance.

Key Features:

• Direct-fit application for 2014-2018 GM Silverado, Sierra, Tahoe, and Yukon models, plus 2019 Limited/Legacy editions
• Large-body design provides maximum oil separation capacity and extended service intervals
• Durable black powder-coated aluminum construction resists corrosion and withstands engine bay temperatures
• Internal baffle system creates cyclonic action to separate oil particles from crankcase vapors
• Easy-drain design with bottom-mounted petcock valve for quick maintenance
• Includes all necessary mounting brackets and hardware for straightforward installation
• Sight glass allows visual monitoring of collected oil level

By capturing oil vapor before it contaminates the intake system, this catch can helps maintain cleaner combustion, reduces carbon deposits, and can improve throttle response. The large reservoir capacity means less frequent draining, making it ideal for trucks used in demanding applications like towing or performance driving.
