The wait is over. You can now upgrade the failure-prone and inadequate PCV Hose system on your Audi B9/B9.5 EA839 V6 Engine with the 034Motorsport PCV Breather Hose upgrade, and for S4, S5, RS4, and RS5 owners, take the upgrade a step further with the 034Motorsport Catch Can Kit.

034Motorsport has spent years reverse engineering, designing, and testing a comprehensive line of PCV system upgrades for the EA839 V6 Engines found in B9/B9.5 Audi's to fix a critical design flaw in the factory PCV hose system that could lead to catastrophic failure. The 034Motorsport PCV Breather Hose cleanly and perfectly remedies these design flaws while offering superior crankcase ventilation for all stages. Whether you're stock or tuned, the 034Motorsport PCV Breather Hose is a critical safety and reliability upgrade. See the product page for details on this design flaw and how the 034Motorsport PCV Breather Hose is the perfect solution.

For those looking to not only remedy the design flaw in the factory PCV system and take PCV System performance a step further, the 034Motorsport Catch Can Kit for B9/B9.5 Audi S4, S5, RS4, and RS5 is the perfect choice. Utilizing the same refined PCV breather hose design and while maintaining both sources of vacuum, the 034Motorsport Catch Can Kit offers great crankcase ventilation while also trapping any oil particulates that would normally escape into the turbo inlet and be burned off. This oil is then drained directly back into the Oil Pan, reducing oil consumption and carbon build-up. See the product page for details on how this works.
