Radium Engineering Dual Side Fluid Lock Oil Catch Can Kit 2002-2014 WRX / 2004-2021 STI / 2004-2013 Forester XT

Keep your intake system clean and maintain peak engine performance with the Radium Dual Catch Can Kit. Designed to separate oil and water condensation from crankcase gasses, this kit prevents oil buildup in the intake, intercooler, throttle body, and intake manifold, helping maintain octane, improve airflow, and reduce hydrocarbon emissions. The closed-loop design also keeps unwanted oil vapors out of the cabin.

Features:

• Direct fitment—no drilling required
• Two independent catch cans for separate PCV system lines
• Large 10AN ORB inlet/outlet ports, 4AN ORB drain port
• Two-step oil separation baffling for maximum efficiency
• O-ring sealed dipstick for easy maintenance
• 7 fl. oz. capacity per can
• Patented Fluid Lock® system for leak-free performance
• Closed-loop system maintains factory plumbing strategy and promotes negative crankcase pressure

How it Works:

• Full throttle/WOT: PCV valve closes, forcing crankcase gasses out of the engine into the turbo inlet. The crankcase catch can collects the most oil during this condition.
• Light/closed throttle: PCV valve opens, allowing fresh air into the crankcase and intake manifold. The PCV line catch can collects oil under these conditions.

Complete installation kit included—everything you need for a clean, efficient, and high-performance PCV system.

Notes:

• For 02-05 Subarus with a cable-actuated throttle body, Radium cruise control relocation bracket must be used
