Radium Engineering PCV Catch Can Kit | 2003-2006 Mitsubishi Evo 8/9

PCV Oil Catch Can Kit by Radium Engineering

The PCV Catch Can Kit installs immediately underneath the RH strut tower and plumbs in-line with the PCV hose.

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.

Please 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 and will withstand any boost level.
