Radium Engineering Crankcase Side Fluid Lock Oil Catch Can

2013–2021 Subaru BRZ, 2022–2024 Subaru BRZ & Toyota GR86

20-0902-FL

Overview:

The Radium Engineering Crankcase Side Fluid Lock Oil Catch Can is designed to improve the performance and longevity of your Subaru BRZ or Toyota GR86 by capturing oil and water condensation from crankcase gases before they enter the intake system. This prevents harmful oil buildup in critical components such as the intake manifold, throttle body, and intercooler system walls, helping maintain cleaner inlet air for better combustion.

Ideal for daily drivers and performance enthusiasts alike, this catch can helps raise effective octane levels, potentially enhancing engine performance while reducing hydrocarbon emissions. Its closed system design also ensures that unwanted oil vapors do not enter the vehicle cabin, maintaining a cleaner and more comfortable driving environment.

Key Features:

This oil catch can offers a range of advanced features engineered for reliability and efficiency:

• Direct bolt-on fitment with no drilling or modifications required for Subaru BRZ (2013–2024) and Toyota GR86 (2022–2024)
• Large 10AN ORB inlet and outlet ports for superior flow capacity
• 4AN ORB drain port for easy and clean oil removal
• Two-step oil separation baffling system to maximize fluid capture and prevent re-entrainment
• O-ring sealed dipstick for secure sealing and easy fluid level checks
• 7 fluid ounce capacity to handle extended intervals between maintenance
• Patented Fluid Lock® system to prevent oil vapors from escaping into the intake or cabin

Construction & Design:

Crafted with precision, the Radium Engineering catch can features robust materials and a compact design tailored for direct fitment on the crankcase side breather port. The system runs inline with the 1/2" breather hose, experiencing atmospheric pressure at low engine loads and vacuum conditions at wide-open throttle (WOT). This design effectively traps crankcase vapors, unspent fuel, and oil sludge that would otherwise contaminate the air intake system.

The two-step baffling system enhances oil separation efficiency, while the O-ring sealed dipstick ensures a tight seal to prevent leaks. The durable construction and thoughtful engineering provide long-lasting performance and reliability under demanding driving conditions.

Installation & Fitment:

This catch can is a direct fit for Subaru BRZ models from 2013 through 2021 and 2022 through 2024, as well as Toyota GR86 models from 2022 through 2024. Installation is straightforward and requires no drilling, cutting, or special tuning. The kit includes all necessary components for a complete installation, allowing you to upgrade your vehicle’s crankcase ventilation system quickly and easily.
