Engine Crankcase Breather Hose Bi-Xenon Improved Performance: Helps maintain engineEngine Crankcase Breather hoses are part of a vehicles Positive Crankcase Ventilation (PCV) system. The job of the PCV system is to allow pressure to escape from the crankcase in a controlled manner.

This blow by gas is routed back into the intake air stream thereby reducing the emission of unburned
