Vorsprung Autowerk Billet PCV Housing for Relocation, Audi 3.0 Supercharged

The factory plastic PCV housing was never designed with long-term durability or custom routing in mind. The Vorsprung Autowerk billet PCV housing adapter replaces the lower section of the original assembly with a precision-machined aluminum component built for strength, reliability, and clean installation.

Engineered as a direct bolt-on upgrade, this adapter provides integrated threaded ports that support a wide range of fitting options, making it easy to configure a proper PCV relocation setup. By replacing the vulnerable plastic section with a rigid billet piece, the system gains improved sealing integrity and resistance to heat and engine bay stress.

Installation is straightforward and requires no permanent modification to the original housing. The result is a cleaner, more serviceable solution that looks purposeful and performs reliably in demanding environments.

Key Highlights:

• Precision-machined billet aluminum construction
