Dual Catch Can Kit

The Radium Engineering Dual Catch Can Kit, model 20-0756-FL, is designed for the 2022+ Subaru WRX VB, offering comprehensive engine protection. This kit integrates both PCV and CCV catch can functionalities to effectively capture oil and water vapor from the crankcase gasses before they are drawn into the intake manifold. By intercepting these contaminants, the kit prevents oil buildup within the intake system, intercooler walls, throttle body, and intake manifold. This leads to cleaner inlet air, which can help raise octane levels, potentially increase engine performance, and reduce hydrocarbon emissions. The closed-loop system also ensures that unwanted oil vapors are kept out of the cabin, maintaining a cleaner interior environment. A key feature is Radium's patented Fluid Lock® technology. This system addresses the common issue of catch can reservoirs overfilling, which can lead to contaminants being released back into the intake system. The Fluid Lock mechanism prevents this overflow, trapping collected fluids until they can be manually emptied, ensuring consistent performance and preventing potential engine issues. Collection intervals vary by vehicle, but Radium recommends checking the integrated dipstick every 3-4 weeks initially to establish a suitable emptying schedule. Emptying can be done by removing the lower reservoir or by installing the optional Petcock Drain Kit. Excessive oil collection may indicate underlying engine issues such as excessive blowby, over-full oil levels, or PCV valve problems. Installation instructions are available in PDF format.
