034Motorsport Catch Can Kit for Audi B9/B9.5 RS5

Upgrade your failure-prone PCV breather hose with the high-performance, 034Motorsport Catch Can Kit, engineered for enhanced durability to capture crankcase oil deposits before entering your intake tract. The 034Motorsport Catch Can Kit isn’t just an upgrade for tuned vehicles - it’s a critical safety enhancement for all EA839-equipped vehicles.

The 034Motorsport Catch Can Kit is designed to replace this PCV breather hose system with a re-engineered breather hose and high-capacity catch can to trap crankcase oil deposits before they enter the turbocharger inlet and charge the air system.
