The 034Motorsport 2.0 TFSI/TSI Valve Cover Breather Adapter is designed to completely eliminate the failure-prone factory oil separator and PCV assembly and offers -10 AN connections to any catch can of your choice.

This part features internally-channeled construction, and connects directly to the factory breather tube going to the turbo inlet.

The Valve Cover Breather Adapter eliminates the breather provision on the intake manifold, eliminating a common source for a boost leak, and preventing oil from entering the intake manifold and contributing to carbon buildup.
