Enhance the reliability of your EA839 engine with the 034Motorsport PCV Breather Hose, designed specifically for Audi S6, S7, RS4, and RS5 models from 2018 to 2024. This component addresses the common failure points of the factory PCV system, ensuring optimal crankcase ventilation and preventing potential engine damage.

Key Features

• Direct replacement for the OE PCV hose, engineered for superior durability.
• High-flow capability to prevent crankcase pressurization, crucial for maintaining engine performance.
• Supports boost pressures of 40+ PSI, making it suitable for both stock and tuned applications.
• Constructed with a CNC-machined, billet aluminum check valve body, finished in black anodized for enhanced corrosion resistance.
• Includes a durable rubber diaphragm that withstands high heat and chemical exposure.
• 4-ply, reinforced silicone hose designed to resist collapsing under vacuum or inflating under boost.

Installation Notes

The installation process for the 034Motorsport PCV Breather Hose is straightforward. It utilizes OE-style multi-use connections, allowing for easy installation and removal, particularly when servicing the turbo inlet. Unlike the OEM solution that often requires additional components, this breather hose is designed to be a long-lasting solution without the need for costly replacements.

Fitment

• Audi S6 C8 2.9 TFSI (2019-2024)
• Audi S7 C8 2.9 TFSI (2019-2024)
• Audi RS4 B9/B9.5 2.9 TFSI (2018-2024)
• Audi RS5 B9/B9.5 2.9 TFSI (2018-2024)

Why Upgrade?

The factory PCV system can be prone to premature failure due to its reliance on check valves that are not designed to handle the demands of turbocharged applications. When these components fail, they can lead to excessive crankcase pressure, potentially resulting in oil leaks or even engine fires. The 034Motorsport PCV Breather Hose mitigates these risks, providing a robust solution that has been extensively tested over two years on various power levels.

With the 034-101-3109 PCV Breather Hose, you gain peace of mind knowing your engine's ventilation system is functioning correctly, whether you are driving a stock model or one equipped with Dynamic+ Stage 1, 2, or 3 tuning.
