PRODUCT DETAILS ▾
RallySport Direct carries highly engineered products designed to improve the performance and longevity of your vehicle brought to you by Radium Engineering.
This is the Radium Engineering Dual Fluid Lock Catch Can Kit. Catch can kits are essential to Subaru platforms to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excessive oil-saturated air circulating back into the air intake stream can lead to degraded performance. The Radium Engineering catch can kit features large 10AN ORB ports, a 4AN ORB drain port, a 2-step oil separation baffling, and an O-ring sealed dipstick.
SPECS:
- Includes (2) independent catch cans that are plumbed into different parts of the PCV system
- The cans do NOT vet to the atmosphere and instead maintain the factory plumbing strategy
- This is a closed-loop system that routes clean filtered air back in through the engine promoting negative crankcase pressure for optimal performance
- Closed-loop systems also prevent unwanted oil vapors from being directed into the cabin
- An aluminum heat shield is provided to prevent radiant exhaust temperatures from disturbing the oil condensation process
- Effectively raises the octane and increased engine performance from cleaner inlet air
- Prevents oil buildup in the intake and intercooler system walls, throttle body, and intake manifold
- Excessive oil collection can be an indicator of a damaged engine
- Lowers hydrocarbon emissions
- Easy servicing with dipsticks
- 7-ounce fluid capacity per can
HIGHLIGHTS:
- This kit is perfect for stock or modified street cars as a preventable measure to keep oil and sludge out of the intake track, intercooler, and intake manifold
- The direct-injected Subaru FA20F engine in particular has an inherent problem since there are no port injectors to clean he backside of the intake valves
- The forward catch can intercepts the CCV line and the rear catch can intercepts the PCV line
- The system is completely sealed and retains the factory function of the PCV valve
- The catch cans are sealed and will withstand pressure in boosted applications
- The kit attaches to the factory mounting provisions on the RH side of the engine bay, and required no permanent modification to the vehicle
NOTES:
- Compatible with the 18-18 Forester XT and 15-21 WRX
- It is not compatible with the 2018+ Sport Lineartronic (CVT) transmission, or STI models
- Has not been tested on RHD models
- May not be compatible with some RHD models
WHY WE CARRY THIS ▾
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT ▾
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
