Radium - Direct-Fit Dual Catch Can Kit for Subaru EJ Turbo (02–21 WRX / STI)

The Radium Engineering Direct-Fit Dual Catch Can Kit for Subaru EJ Turbo (2002–2021 WRX / STI) resolves one of the most critical weaknesses of the boxer engine platform: heavy crankcase blow-by ingestion during track driving and high-boost acceleration. By separating oil mist from both the PCV and crankcase breather circuits independently, this kit stops oil coating of the top-mount or front-mount intercooler and prevents oil-induced detonation.

Key Performance Features:

• Dual Independent Circuit Filtration: One can manages the high-vacuum PCV circuit while the second can manages the crankcase/valve cover breather circuit under full boost.
• Fluid Lock Anti-Surge Baffling: Prevents captured oil from re-entering the intake tract under heavy high-G cornering and hard braking.
• Chassis-Specific Mounting: Direct bolt-on bracket mounts both canisters neatly in the engine bay without interfering with factory brake booster or strut bars.
• Pre-Formed Hoses & Fittings: Includes complete application-specific rubber lines, barb fittings, and clamps for a seamless install.
• Integrated Dipsticks: Quick-check fluid level dipsticks allow visual inspection in seconds without disassembling canisters.

Vehicle & Engine Compatibility:

• 2002–2007 Subaru WRX / STI (GD / GG) - EJ205 / EJ257
• 2008–2014 Subaru WRX / STI (GR / GV / GH) - EJ255 / EJ257
• 2015–2021 Subaru STI (VA) - EJ257
• 2004–2008 Subaru Forester XT - EJ255

Notice: Standard closed-loop plumbing maintains emissions compliance and eliminates raw fuel/oil odors in the vehicle cabin.
