CATCH CAN KITS, 15-21 WRX

COMPATIBILITY

Not compatible with some Sport Lineartronic (CVT) Transmission models. Some models will have a control module that is mounted in the same location that the catch cans will install into. Compare the photo of the catch can install location to the vehicles engine bay before ordering.

Not compatible with the Subaru STi
Has not been tested on right hand drive models
May not be compatible with some aftermarket intake systems

OVERVIEW

This kit is perfect for stock or modified street cars as a preventative measure to keep oil and sludge out of the intake tract, intercooler, and intake manifold. The direct-injected Subaru FA20F engine in particular has an inherent problem since there are no port injectors to clean the 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 factory function of the PCV valve. The catch cans are sealed and will withstand pressure in boosted applications.

The catch can draws out oil and water condensation from the crankcase gasses that would otherwise be drawn into the intake manifold. This prevents oil buildup in the intake, intercooler system walls, throttle body, and intake manifold. This effectively raises the octane, can increase engine performance from cleaner inlet air, and can lower hydrocarbon emissions. The closed system prevents unwanted oil vapors from entering into the cabin. Catch can kits include everything needed for a complete installation.

FLUID LOCK® CATCH CANS

In 2022, Radium Engineering implemented a revolutionary design change to the 7 fluid ounce standard catch can. An inherent problem always existed with typical catch cans when not serviced regularly. The fluid contaminants will eventually leave the reservoir pouring into the air intake system causing poor engine performance. To resolve this issue, Radium created the Fluid Lock® Catch Can. This contains a patented mechanism that prevents the reservoir from overfilling and traps the collected fluids until it is emptied.

COLLECTION & EMPTYING

The rate that your catch cans will collect oil and moisture contaminants will vary from one individual vehicle to the next, so there is no set emptying interval. PCV catch cans tend to collect more than CCV catch cans. You should check the level of your catch can using the integrated dipstick starting at 3-4 weeks of driving and repeat as needed to determine how often they should be emptied based on what you see.

Catch cans can be emptied by unscrewing the lower reservoir and removing it from the vehicle to dump out, or in cases where there is available space under the catch can, the Petcock Drain Kit can be installed and used to drain them.

In cases where oil collection is excessive you may have to address an issue with the engine. The reasons a catch can will collect an excess of oil include

• Excessive blowby from engine damage
• Crankcase windage from an over-full oil level
• Poor placement of breather ports and/or poor baffling inside breather ports
• PCV valve not closing and leaking under heavy load
