PCV Oil Catch Can Dual Kit for Subaru WRX 15-21 Fluid Lock Radium Engineering

COMPATIBILITY* 2015-2021 Subaru WRX. Not compatible with Subaru STi. Not tested on right-hand drive models. May not be compatible with some aftermarket intake systems.* Not compatible with 2018+ Sport Lineartronic (CVT) transmission.

An oil catch can is essential in a high-performance vehicle to protect the engine from the high levels of crankcase blow-by accumulated during spirited driving. Excess oil-saturated air recirculating into the intake system can lead to diminished performance. Radium Engineering Catch Cans feature large 10AN ORB ports, a 4AN ORB drain port, two-stage oil separation baffling, and an O-ring sealed dipstick.
Features: - Effectively increases octane and engine performance from cleaner intake air. - Prevents oil buildup on intake system and intercooler walls, throttle body, intake manifold, etc. - Excessive oil buildup can indicate a damaged engine. - Reduces hydrocarbon emissions. - Capacity: 200ml each.

This kit is ideal for street cars, both stock and modified, as a preventative measure to keep oil and sludge out of the intake system, intercooler, and intake manifold. The direct-injected Subaru FA20F engine, in particular, has an inherent problem since it does not have port injectors to clean the back of the intake valves. The front catch can intercepts the CCV line and the rear catch can intercepts the PCV line. The system is completely sealed and retains the original PCV valve functionality. The catch cans are sealed and support pressure in turbocharged applications.
