Radium Engineering’s single catch can kit for Mitsubishi Evo IV–VI mounts to the firewall and interfaces with the engine’s PCV hose to capture oil and vapor. It uses Radium’s patented 7 oz Fluid-Lock catch can and is designed for compact, firewall-mounted installation to help prevent oil contamination of intake plumbing on Evo versions 4 through 6.
