The SpeedFactory Racing Naturally Aspirated Catch Can is designed to work with any B-Series naturally aspirated (non-supercharged, non-turbocharged) engine setup. This breather setup is engineered to provide the sufficient crankcase ventilation your high performance engine needs, and also condenses crankcase blow-by oil and moisture correctly. The factory PCV system is replaced and all oil vapors are vented to the atmosphere through the single filter.
