PCV Catch Can Kit for Honda Civic Type R Fluid Lock Radium Engineering
Compatibility
- 2017–2021 Honda Civic Type R FK8 (left-hand drive only)
- 2023+ Honda Civic Type R FL5 (left-hand drive only)
Overview
Radium Engineering Fluid Lock® catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick.
The PCV and CCV catch can systems operate independently and are available individually or as a complete dual kit. These closed-loop systems do not vent to atmosphere (VTA), making them emissions and track legal while promoting negative crankcase pressure and preventing unwanted oil vapors from entering the cabin.
The kit mounts using factory mounting locations and requires no cutting, drilling, or permanent vehicle modifications.

Description
The 20-0424-FL PCV Catch Can Kit mounts to the right-hand firewall using factory mounting points with no modifications required.
The catch can installs inline with the factory positive crankcase ventilation (PCV) valve while retaining full OEM functionality.
When intake manifold pressure is at or above atmospheric pressure, the PCV check valve closes and no flow occurs through the PCV hose. During idle, steady-state cruising, and deceleration, the PCV system experiences metered vacuum that would normally draw crankcase vapors, unburned fuel, and oil sludge into the intake manifold.
The Fluid Lock® catch can captures these contaminants before they reach the intake system, helping maintain cleaner intake components and supporting long-term engine performance.
Because the Fluid Lock® catch can is pressure sealed, no additional inline check valve is required, allowing direct connection to the intake manifold.
