Radium Engineering Fluid Lock Catch Can Kit (PCV) - Honda Civic Type R (FK8 / FL5)
The Radium Engineering Fluid Lock PCV catch can kit (SKU 20-0424-FL) is built for the Honda Civic Type R FK8 and FL5. It runs inline with the PCV valve and keeps its factory function, catching crankcase vapour, unspent fuel and oil sludge that would otherwise be drawn into the intake manifold at idle, cruise and deceleration.

The can secures to the right-hand firewall with no modifications. Radium catch cans are pressure sealed, so no inline check valve is needed and a direct intake manifold connection is permitted. A companion CCV kit is available separately, and Radium recommends running both for maximum protection.
Note: Radium states this kit is designed for left-hand-drive vehicles. Designed around the US-market vehicle; please confirm fitment on Australian-delivered vehicles with our team before ordering. Installation by a professional is recommended.
