Billet PCV Breather Fitting for Audi 3.0T

Upgrade the weak points in your Audi 3.0T PCV system with a billet breather fitting designed for custom AN conversions. This fitting makes it easy to replace the factory-style plastic hose connection with a more secure, serviceable solution for custom catch can setups and other performance-focused crankcase ventilation configurations.

Built for reliability, this fitting features an oversized sealing design with dual Viton O-rings to help ensure a tight, leak-free fit under demanding conditions. A billet locking mechanism adds another layer of security, helping keep the fitting properly seated and sealed once installed. The result is a cleaner, stronger alternative to failure-prone plastic components, with the durability needed for long-term use.
