Vorsprung Autowerk Billet PCV Housing Adapter – Audi 3.0T

The Permanent Fix for 3.0T PCV Failures

The factory plastic PCV housing on the supercharged Audi 3.0T is notorious for becoming brittle, cracking, and failing under the intense heat of the engine valley. Designed with long-term durability in mind, the Vorsprung Autowerk Billet PCV Housing Adapter permanently solves this issue. By replacing the vulnerable lower section of your original assembly with a precision-machined aluminum component, you ensure you won't be pulling your supercharger again just to fix cracked plastic.

Engineered for Custom 3.0T PCV Relocation

Whether you are running higher boost, building a track car, or just want easier maintenance, this adapter is built for clean, custom installations. Engineered as a direct bolt-on upgrade, it features integrated threaded ports that support a wide range of AN fittings and aftermarket lines. This makes configuring a proper PCV relocation setup or catch can system incredibly straightforward.

By upgrading to a rigid billet piece, your 3.0T gains superior sealing integrity and high heat resistance. Installation requires no adhesives, cutting, or permanent modification to the original housing. The result is a highly serviceable solution that looks purposeful and performs reliably in demanding, high-horsepower environments.
