WARNING: Cancer and Reproductive Harm www.P65Warnings.ca.gov

An Air/Oil Separator is designed for one task.  That task is to remove any unwanted oil from the engine's ventilation system so the oil does not get sent through the intake system. By reducing the amount of oil headed for the intake system, you give your engines ability to perform cleaner and more efficiently.  BLOX Racing's Air/Oil separator is a direct factory bolt on item, requiring minimal modifications to the OEM PCV system.  

* This unit is made out of aluminum.*
