Designed with simplicity of install in mind the BSH Bulletproof PCV Stage 2 kit takes our already successful PCV program one step further. Manufactured here in the US, the CNC machined BSH Bulletproof PCV Stage 2 fixes all the major problems associated with the prone to failure PCV system and adds a true catch can to capture all oil vapors that would otherwise make their way back into the engine. This package is the ideal performance solution for those who want the most out of their tuned 2.0T! This is the upgrade kit only! You must have the Stage 1 Kit to run this. IMPORTANT NOTE: Customers in regions of the world that drop into the freezing or near freezing temperatures during the winter will need to keep a watchful eye on the volume of water collected in the can. One of the main fluids caught in the can is condensation (water). In the winter months the amount of condensation caught in the can will dramatically increase. If left in the can in freezing temperatures there is a possibility that this water could freeze. If frozen, pcv flow will be inhibited. Make sure to keep an eye on your fluid levels.
