Designed with simplicity of install in mind the BSH Bulletproof PCV Revamp kit takes care of the commonly occurring PCV issues in tuned 2.0T applications. Manufactured here in the US, the CNC machined BSH Bulletproof PCV Revamp fixes the major problems with the 2.0T PCV system once and for all! The prone to failure factory PCV system has long plagued this engine with poor mpg, rough idle, boost loss, and the dreaded oil spewing from the oil cap. The BSH Bulletproof PCV revamp ensures these issues will never affect your engine again by converting the system to a vacuum only based system. PCV function is properly retained and no emissions functions are tampered with this modification. Also check out the BSH stage 2 kit which incorporates a catch can!
