The factory PCV system on VQ engines recirculates crankcase vapors back into your intake — causing carbon buildup on your throttle body, intake manifold, and valves over time. This baffled catch can system eliminates that problem and adds a dedicated coolant reservoir, keeping your engine cleaner and your cooling system properly managed in one clean install.

Key Benefits

• Eliminates oil and crankcase vapors from entering your intake system — prevents carbon buildup on throttle body, manifold, and valves
• Baffled design separates oil from air more effectively than standard catch cans
• Integrated coolant reservoir replaces the factory overflow bottle for cleaner engine bay presentation
• Collects E85 fuel vapors if running ethanol — prevents vapor buildup in the intake tract
• Fully customizable — choose your filter color and fitting/line combo at checkout
