Radium Engineering Catch Can Kit PCV for 2017-2024 Civic Type-R FK8 FL5

Single catch can kit for the Honda Civic Type-R (FK8). Interfaces with the PCV hose. All fittings, hoses and hardware included for an easy bolt-in installation. Includes Radium's Fluid Lock catch can (patent pending).

This catch can runs inline with the PCV (positive crankcase ventilation) valve and retains it's factory function. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience "metered" vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run. Note: No inline check valve is required since Radium catch cans are pressure sealed. This means a direct intake manifold connection is permitted.
