Choose Your Catch Can Kit
- PCV Catch Can, 20-0749-FL: Installs inline on the positive crankcase ventilation side, between the ventilation valve and intake pipe. This is the entry-level single-can option.
- CCV Catch Can, 20-0750-FL: Installs inline between the crankcase vent port and intake pipe to collect oil and sludge from the CCV side, particularly under higher engine load.
- Dual Catch Can Kit, 20-0751-FL: Includes both the PCV and CCV catch can kits for complete coverage of both crankcase ventilation paths. This is Radium’s recommended configuration for the most complete oil-separation setup.

Product Description
The GR Supra’s B58 uses both PCV and CCV crankcase ventilation paths. Oil vapor and condensation carried through those paths can leave residue in the intake tract, charge-air system, throttle body, and intake manifold over time. Radium’s catch can kits separate those contaminants before the air is routed back into the engine.
Each option mounts at the front radiator support, away from common aftermarket parts such as upgraded turbochargers, intake tubing, and strut braces. The systems stay closed-loop, so they preserve the intended crankcase ventilation function rather than venting oil vapor into the engine bay.
The Fluid Lock design is especially useful on a street-driven car because it is designed to prevent collected contaminants from escaping the catch can reservoir and entering the intake if service is delayed. The integrated dipstick makes it easy to check the collected fluid during normal maintenance.
