Radium Engineering Catch Can Kit S2000 All RHD and 06-09 LHD PCV Fluid Lock

The PCV kit comes with 2 mounting brackets. One bracket will be disregarded depending if the crankcase vent kit will also be used. This catch can runs inline with the 3/8" PCV (positive crankcase ventilation) valve. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience 'metered' vacuum when the engine is idling, low load 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: Because the Radium catch cans are pressure sealed, they are great for boosted applications as well so connecting to the intake manifold is permitted.
